Introduction
Laravel Passport provides a full OAuth2 server implementation for your Laravel application in a matter of minutes. Passport is built on top of the League OAuth2 server that is maintained by Andy Millington and Simon Hamp.
{note} This documentation assumes you are already familiar with OAuth2. If you do not know anything about OAuth2, consider familiarizing yourself with the general terminology and features of OAuth2 before continuing.
Passport Or Sanctum?
Before getting started, you may wish to determine if your application would be better served by Laravel Passport or Laravel Sanctum. If your application absolutely needs to support OAuth2, then you should use Laravel Passport.
However, if you are attempting to authenticate a single-page application, mobile application, or issue API tokens, you should use Laravel Sanctum. Laravel Sanctum does not support OAuth2; however, it provides a much simpler API authentication development experience.
Installation
To get started, install Passport via the Composer package manager:
composer require laravel/passport
Passport's service provider registers its own database migration directory, so you should migrate your database after installing the package. The Passport migrations will create the tables your application needs to store OAuth2 clients and access tokens:
php artisan migrate
Next, you should execute the passport:install
Artisan command. This command will create the encryption keys needed to generate secure access tokens. In addition, the command will create "personal access" and "password grant" clients which will be used to generate access tokens:
php artisan passport:install
{tip} If you would like to use UUIDs as the primary key value of the Passport
Client
model instead of auto-incrementing integers, please install Passport using theuuids
option.
After running the passport:install
command, add the Laravel\Passport\HasApiTokens
trait to your App\Models\User
model. This trait will provide a few helper methods to your model which allow you to inspect the authenticated user's token and scopes. If your model is already using the Laravel\Sanctum\HasApiTokens
trait, you may remove that trait:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Passport\HasApiTokens;
class User extends Authenticatable
{
use HasApiTokens, HasFactory, Notifiable;
}
Next, you should call the Passport::routes
method within the boot
method of your App\Providers\AuthServiceProvider
. This method will register the routes necessary to issue access tokens and revoke access tokens, clients, and personal access tokens:
<?php
namespace App\Providers;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
use Illuminate\Support\Facades\Gate;
use Laravel\Passport\Passport;
class AuthServiceProvider extends ServiceProvider
{
/**
* The policy mappings for the application.
*
* @var array
*/
protected $policies = [
'App\Models\Model' => 'App\Policies\ModelPolicy',
];
/**
* Register any authentication / authorization services.
*
* @return void
*/
public function boot()
{
$this->registerPolicies();
if (! $this->app->routesAreCached()) {
Passport::routes();
}
}
}
Finally, in your application's config/auth.php
configuration file, you should set the driver
option of the api
authentication guard to passport
. This will instruct your application to use Passport's TokenGuard
when authenticating incoming API requests:
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'passport',
'provider' => 'users',
],
],
Client UUIDs
You may also run the passport:install
command with the --uuids
option present. This option will instruct Passport that you would like to use UUIDs instead of auto-incrementing integers as the Passport Client
model's primary key values. After running the passport:install
command with the --uuids
option, you will be given additional instructions regarding disabling Passport's default migrations:
php artisan passport:install --uuids
Deploying Passport
When deploying Passport to your application's servers for the first time, you will likely need to run the passport:keys
command. This command generates the encryption keys Passport needs in order to generate access tokens. The generated keys are not typically kept in source control:
php artisan passport:keys
If necessary, you may define the path where Passport's keys should be loaded from. You may use the Passport::loadKeysFrom
method to accomplish this. Typically, this method should be called from the boot
method of your application's App\Providers\AuthServiceProvider
class:
/**
* Register any authentication / authorization services.
*
* @return void
*/
public function boot()
{
$this->registerPolicies();
Passport::routes();
Passport::loadKeysFrom(__DIR__.'/../secrets/oauth');
}
Loading Keys From The Environment
Alternatively, you may publish Passport's configuration file using the vendor:publish
Artisan command:
php artisan vendor:publish --tag=passport-config
After the configuration file has been published, you may load your application's encryption keys by defining them as environment variables:
PASSPORT_PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----
<private key here>
-----END RSA PRIVATE KEY-----"
PASSPORT_PUBLIC_KEY="-----BEGIN PUBLIC KEY-----
<public key here>
-----END PUBLIC KEY-----"
Migration Customization
If you are not going to use Passport's default migrations, you should call the Passport::ignoreMigrations
method in the register
method of your App\Providers\AppServiceProvider
class. You may export the default migrations using the vendor:publish
Artisan command:
php artisan vendor:publish --tag=passport-migrations
Upgrading Passport
When upgrading to a new major version of Passport, it's important that you carefully review the upgrade guide.
Configuration
Client Secret Hashing
If you would like your client's secrets to be hashed when stored in your database, you should call the Passport::hashClientSecrets
method in the boot
method of your App\Providers\AuthServiceProvider
class:
use Laravel\Passport\Passport;
Passport::hashClientSecrets();
Once enabled, all of your client secrets will only be displayable to the user immediately after they are created. Since the plain-text client secret value is never stored in the database, it is not possible to recover the secret's value if it is lost.
Token Lifetimes
By default, Passport issues long-lived access tokens that expire after one year. If you would like to configure a longer / shorter token lifetime, you may use the tokensExpireIn
, refreshTokensExpireIn
, and personalAccessTokensExpireIn
methods. These methods should be called from the boot
method of your application's App\Providers\AuthServiceProvider
class:
/**
* Register any authentication / authorization services.
*
* @return void
*/
public function boot()
{
$this->registerPolicies();
Passport::routes();
Passport::tokensExpireIn(now()->addDays(15));
Passport::refreshTokensExpireIn(now()->addDays(30));
Passport::personalAccessTokensExpireIn(now()->addMonths(6));
}
{note} The
expires_at
columns on Passport's database tables are read-only and for display purposes only. When issuing tokens, Passport stores the expiration information within the signed and encrypted tokens. If you need to invalidate a token you should revoke it.
Overriding Default Models
You are free to extend the models used internally by Passport by defining your own model and extending the corresponding Passport model:
use Laravel\Passport\Client as PassportClient;
class Client extends PassportClient
{
// ...
}
After defining your model, you may instruct Passport to use your custom model via the Laravel\Passport\Passport
class. Typically, you should inform Passport about your custom models in the boot
method of your application's App\Providers\AuthServiceProvider
class:
use App\Models\Passport\AuthCode;
use App\Models\Passport\Client;
use App\Models\Passport\PersonalAccessClient;
use App\Models\Passport\Token;
/**
* Register any authentication / authorization services.
*
* @return void
*/
public function boot()
{
$this->registerPolicies();
Passport::routes();
Passport::useTokenModel(Token::class);
Passport::useClientModel(Client::class);
Passport::useAuthCodeModel(AuthCode::class);
Passport::usePersonalAccessClientModel(PersonalAccessClient::class);
}
Issuing Access Tokens
Using OAuth2 via authorization codes is how most developers are familiar with OAuth2. When using authorization codes, a client application will redirect a user to your server where they will either approve or deny the request to issue an access token to the client.
Managing Clients
First, developers building applications that need to interact with your application's API will need to register their application with yours by creating a "client". Typically, this consists of providing the name of their application and a URL that your application can redirect to after users approve their request for authorization.
The passport:client
Command
The simplest way to create a client is using the passport:client
Artisan command. This command may be used to create your own clients for testing your OAuth2 functionality. When you run the client
command, Passport will prompt you for more information about your client and will provide you with a client ID and secret:
php artisan passport:client
Redirect URLs
If you would like to allow multiple redirect URLs for your client, you may specify them using a comma-delimited list when prompted for the URL by the passport:client
command. Any URLs which contain commas should be URL encoded:
http://example.com/callback,http://examplefoo.com/callback
JSON API
Since your application's users will not be able to utilize the client
command, Passport provides a JSON API that you may use to create clients. This saves you the trouble of having to manually code controllers for creating, updating, and deleting clients.
However, you will need to pair Passport's JSON API with your own frontend to provide a dashboard for your users to manage their clients. Below, we'll review all of the API endpoints for managing clients. For convenience, we'll use Axios to demonstrate making HTTP requests to the endpoints.
The JSON API is guarded by the web
and auth
middleware; therefore, it may only be called from your own application. It is not able to be called from an external source.
GET /oauth/clients
This route returns all of the clients for the authenticated user. This is primarily useful for listing all of the user's clients so that they may edit or delete them:
axios.get('/oauth/clients')
.then(response => {
console.log(response.data);
});
POST /oauth/clients
This route is used to create new clients. It requires two pieces of data: the client's name
and a redirect
URL. The redirect
URL is where the user will be redirected after approving or denying a request for authorization.
When a client is created, it will be issued a client ID and client secret. These values will be used when requesting access tokens from your application. The client creation route will return the new client instance:
const data = {
name: 'Client Name',
redirect: 'http://example.com/callback'
};
axios.post('/oauth/clients', data)
.then(response => {
console.log(response.data);
})
.catch (response => {
// List errors on response...
});
PUT /oauth/clients/{client-id}
This route is used to update clients. It requires two pieces of data: the client's name
and a redirect
URL. The redirect
URL is where the user will be redirected after approving or denying a request for authorization. The route will return the updated client instance:
const data = {
name: 'New Client Name',
redirect: 'http://example.com/callback'
};
axios.put('/oauth/clients/' + clientId, data)
.then(response => {
console.log(response.data);
})
.catch (response => {
// List errors on response...
});
DELETE /oauth/clients/{client-id}
This route is used to delete clients:
axios.delete('/oauth/clients/' + clientId)
.then(response => {
//
});
Requesting Tokens
Redirecting For Authorization
Once a client has been created, developers may use their client ID and secret to request an authorization code and access token from your application. First, the consuming application should make a redirect request to your application's /oauth/authorize
route like so:
use Illuminate\Http\Request;
use Illuminate\Support\Str;
Route::get('/redirect', function (Request $request) {
$request->session()->put('state', $state = Str::random(40));
$query = http_build_query([
'client_id' => 'client-id',
'redirect_uri' => 'http://third-party-app.com/callback',
'response_type' => 'code',
'scope' => '',
'state' => $state,
]);
return redirect('http://passport-app.test/oauth/authorize?'.$query);
});
{tip} Remember, the
/oauth/authorize
route is already defined by thePassport::routes
method. You do not need to manually define this route.
Approving The Request
When receiving authorization requests, Passport will automatically display a template to the user allowing them to approve or deny the authorization request. If they approve the request, they will be redirected back to the redirect_uri
that was specified by the consuming application. The redirect_uri
must match the redirect
URL that was specified when the client was created.
If you would like to customize the authorization approval screen, you may publish Passport's views using the vendor:publish
Artisan command. The published views will be placed in the resources/views/vendor/passport
directory:
php artisan vendor:publish --tag=passport-views
Sometimes you may wish to skip the authorization prompt, such as when authorizing a first-party client. You may accomplish this by extending the Client
model and defining a skipsAuthorization
method. If skipsAuthorization
returns true
the client will be approved and the user will be redirected back to the redirect_uri
immediately:
<?php
namespace App\Models\Passport;
use Laravel\Passport\Client as BaseClient;
class Client extends BaseClient
{
/**
* Determine if the client should skip the authorization prompt.
*
* @return bool
*/
public function skipsAuthorization()
{
return $this->firstParty();
}
}
Converting Authorization Codes To Access Tokens
If the user approves the authorization request, they will be redirected back to the consuming application. The consumer should first verify the state
parameter against the value that was stored prior to the redirect. If the state parameter matches then the consumer should issue a POST
request to your application to request an access token. The request should include the authorization code that was issued by your application when the user approved the authorization request:
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Http;
Route::get('/callback', function (Request $request) {
$state = $request->session()->pull('state');
throw_unless(
strlen($state) > 0 && $state === $request->state,
InvalidArgumentException::class
);
$response = Http::asForm()->post('http://passport-app.test/oauth/token', [
'grant_type' => 'authorization_code',
'client_id' => 'client-id',
'client_secret' => 'client-secret',
'redirect_uri' => 'http://third-party-app.com/callback',
'code' => $request->code,
]);
return $response->json();
});
This /oauth/token
route will return a JSON response containing access_token
, refresh_token
, and expires_in
attributes. The expires_in
attribute contains the number of seconds until the access token expires.
{tip} Like the
/oauth/authorize
route, the/oauth/token
route is defined for you by thePassport::routes
method. There is no need to manually define this route.
JSON API
Passport also includes a JSON API for managing authorized access tokens. You may pair this with your own frontend to offer your users a dashboard for managing access tokens. For convenience, we'll use Axios to demonstrate making HTTP requests to the endpoints. The JSON API is guarded by the web
and auth
middleware; therefore, it may only be called from your own application.
GET /oauth/tokens
This route returns all of the authorized access tokens that the authenticated user has created. This is primarily useful for listing all of the user's tokens so that they can revoke them:
axios.get('/oauth/tokens')
.then(response => {
console.log(response.data);
});
DELETE /oauth/tokens/{token-id}
This route may be used to revoke authorized access tokens and their related refresh tokens:
axios.delete('/oauth/tokens/' + tokenId);
Refreshing Tokens
If your application issues short-lived access tokens, users will need to refresh their access tokens via the refresh token that was provided to them when the access token was issued:
use Illuminate\Support\Facades\Http;
$response = Http::asForm()->post('http://passport-app.test/oauth/token', [
'grant_type' => 'refresh_token',
'refresh_token' => 'the-refresh-token',
'client_id' => 'client-id',
'client_secret' => 'client-secret',
'scope' => '',
]);
return $response->json();
This /oauth/token
route will return a JSON response containing access_token
, refresh_token
, and expires_in
attributes. The expires_in
attribute contains the number of seconds until the access token expires.
Revoking Tokens
You may revoke a token by using the revokeAccessToken
method on the Laravel\Passport\TokenRepository
. You may revoke a token's refresh tokens using the revokeRefreshTokensByAccessTokenId
method on the Laravel\Passport\RefreshTokenRepository
. These classes may be resolved using Laravel's service container:
use Laravel\Passport\TokenRepository;
use Laravel\Passport\RefreshTokenRepository;
$tokenRepository = app(TokenRepository::class);
$refreshTokenRepository = app(RefreshTokenRepository::class);
// Revoke an access token...
$tokenRepository->revokeAccessToken($tokenId);
// Revoke all of the token's refresh tokens...
$refreshTokenRepository->revokeRefreshTokensByAccessTokenId($tokenId);
Purging Tokens
When tokens have been revoked or expired, you might want to purge them from the database. Passport's included passport:purge
Artisan command can do this for you:
# Purge revoked and expired tokens and auth codes...
php artisan passport:purge
# Only purge revoked tokens and auth codes...
php artisan passport:purge --revoked
# Only purge expired tokens and auth codes...
php artisan passport:purge --expired
You may also configure a scheduled job in your application's App\Console\Kernel
class to automatically prune your tokens on a schedule:
/**
* Define the application's command schedule.
*
* @param \Illuminate\Console\Scheduling\Schedule $schedule
* @return void
*/
protected function schedule(Schedule $schedule)
{
$schedule->command('passport:purge')->hourly();
}
Authorization Code Grant with PKCE
The Authorization Code grant with "Proof Key for Code Exchange" (PKCE) is a secure way to authenticate single page applications or native applications to access your API. This grant should be used when you can't guarantee that the client secret will be stored confidentially or in order to mitigate the threat of having the authorization code intercepted by an attacker. A combination of a "code verifier" and a "code challenge" replaces the client secret when exchanging the authorization code for an access token.
Creating The Client
Before your application can issue tokens via the authorization code grant with PKCE, you will need to create a PKCE-enabled client. You may do this using the passport:client
Artisan command with the --public
option:
php artisan passport:client --public
Requesting Tokens
Code Verifier & Code Challenge
As this authorization grant does not provide a client secret, developers will need to generate a combination of a code verifier and a code challenge in order to request a token.
The code verifier should be a random string of between 43 and 128 characters containing letters, numbers, and "-"
, "."
, "_"
, "~"
characters, as defined in the RFC 7636 specification.
The code challenge should be a Base64 encoded string with URL and filename-safe characters. The trailing '='
characters should be removed and no line breaks, whitespace, or other additional characters should be present.
$encoded = base64_encode(hash('sha256', $code_verifier, true));
$codeChallenge = strtr(rtrim($encoded, '='), '+/', '-_');
Redirecting For Authorization
Once a client has been created, you may use the client ID and the generated code verifier and code challenge to request an authorization code and access token from your application. First, the consuming application should make a redirect request to your application's /oauth/authorize
route:
use Illuminate\Http\Request;
use Illuminate\Support\Str;
Route::get('/redirect', function (Request $request) {
$request->session()->put('state', $state = Str::random(40));
$request->session()->put(
'code_verifier', $code_verifier = Str::random(128)
);
$codeChallenge = strtr(rtrim(
base64_encode(hash('sha256', $code_verifier, true))
, '='), '+/', '-_');
$query = http_build_query([
'client_id' => 'client-id',
'redirect_uri' => 'http://third-party-app.com/callback',
'response_type' => 'code',
'scope' => '',
'state' => $state,
'code_challenge' => $codeChallenge,
'code_challenge_method' => 'S256',
]);
return redirect('http://passport-app.test/oauth/authorize?'.$query);
});
Converting Authorization Codes To Access Tokens
If the user approves the authorization request, they will be redirected back to the consuming application. The consumer should verify the state
parameter against the value that was stored prior to the redirect, as in the standard Authorization Code Grant.
If the state parameter matches, the consumer should issue a POST
request to your application to request an access token. The request should include the authorization code that was issued by your application when the user approved the authorization request along with the originally generated code verifier:
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Http;
Route::get('/callback', function (Request $request) {
$state = $request->session()->pull('state');
$codeVerifier = $request->session()->pull('code_verifier');
throw_unless(
strlen($state) > 0 && $state === $request->state,
InvalidArgumentException::class
);
$response = Http::asForm()->post('http://passport-app.test/oauth/token', [
'grant_type' => 'authorization_code',
'client_id' => 'client-id',
'redirect_uri' => 'http://third-party-app.com/callback',
'code_verifier' => $codeVerifier,
'code' => $request->code,
]);
return $response->json();
});
Password Grant Tokens
The OAuth2 password grant allows your other first-party clients, such as a mobile application, to obtain an access token using an email address / username and password. This allows you to issue access tokens securely to your first-party clients without requiring your users to go through the entire OAuth2 authorization code redirect flow.
Creating A Password Grant Client
Before your application can issue tokens via the password grant, you will need to create a password grant client. You may do this using the passport:client
Artisan command with the --password
option. If you have already run the passport:install
command, you do not need to run this command:
php artisan passport:client --password
Requesting Tokens
Once you have created a password grant client, you may request an access token by issuing a POST
request to the /oauth/token
route with the user's email address and password. Remember, this route is already registered by the Passport::routes
method so there is no need to define it manually. If the request is successful, you will receive an access_token
and refresh_token
in the JSON response from the server:
use Illuminate\Support\Facades\Http;
$response = Http::asForm()->post('http://passport-app.test/oauth/token', [
'grant_type' => 'password',
'client_id' => 'client-id',
'client_secret' => 'client-secret',
'username' => 'taylor@laravel.com',
'password' => 'my-password',
'scope' => '',
]);
return $response->json();
{tip} Remember, access tokens are long-lived by default. However, you are free to configure your maximum access token lifetime if needed.
Requesting All Scopes
When using the password grant or client credentials grant, you may wish to authorize the token for all of the scopes supported by your application. You can do this by requesting the *
scope. If you request the *
scope, the can
method on the token instance will always return true
. This scope may only be assigned to a token that is issued using the password
or client_credentials
grant:
use Illuminate\Support\Facades\Http;
$response = Http::asForm()->post('http://passport-app.test/oauth/token', [
'grant_type' => 'password',
'client_id' => 'client-id',
'client_secret' => 'client-secret',
'username' => 'taylor@laravel.com',
'password' => 'my-password',
'scope' => '*',
]);
Customizing The User Provider
If your application uses more than one authentication user provider, you may specify which user provider the password grant client uses by providing a --provider
option when creating the client via the artisan passport:client --password
command. The given provider name should match a valid provider defined in your application's config/auth.php
configuration file. You can then protect your route using middleware to ensure that only users from the guard's specified provider are authorized.
Customizing The Username Field
When authenticating using the password grant, Passport will use the email
attribute of your authenticatable model as the "username". However, you may customize this behavior by defining a findForPassport
method on your model:
<?php
namespace App\Models;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Passport\HasApiTokens;
class User extends Authenticatable
{
use HasApiTokens, Notifiable;
/**
* Find the user instance for the given username.
*
* @param string $username
* @return \App\Models\User
*/
public function findForPassport($username)
{
return $this->where('username', $username)->first();
}
}
Customizing The Password Validation
When authenticating using the password grant, Passport will use the password
attribute of your model to validate the given password. If your model does not have a password
attribute or you wish to customize the password validation logic, you can define a validateForPassportPasswordGrant
method on your model:
<?php
namespace App\Models;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Illuminate\Support\Facades\Hash;
use Laravel\Passport\HasApiTokens;
class User extends Authenticatable
{
use HasApiTokens, Notifiable;
/**
* Validate the password of the user for the Passport password grant.
*
* @param string $password
* @return bool
*/
public function validateForPassportPasswordGrant($password)
{
return Hash::check($password, $this->password);
}
}
Implicit Grant Tokens
The implicit grant is similar to the authorization code grant; however, the token is returned to the client without exchanging an authorization code. This grant is most commonly used for JavaScript or mobile applications where the client credentials can't be securely stored. To enable the grant, call the enableImplicitGrant
method in the boot
method of your application's App\Providers\AuthServiceProvider
class:
/**
* Register any authentication / authorization services.
*
* @return void
*/
public function boot()
{
$this->registerPolicies();
Passport::routes();
Passport::enableImplicitGrant();
}
Once the grant has been enabled, developers may use their client ID to request an access token from your application. The consuming application should make a redirect request to your application's /oauth/authorize
route like so:
use Illuminate\Http\Request;
Route::get('/redirect', function (Request $request) {
$request->session()->put('state', $state = Str::random(40));
$query = http_build_query([
'client_id' => 'client-id',
'redirect_uri' => 'http://third-party-app.com/callback',
'response_type' => 'token',
'scope' => '',
'state' => $state,
]);
return redirect('http://passport-app.test/oauth/authorize?'.$query);
});
{tip} Remember, the
/oauth/authorize
route is already defined by thePassport::routes
method. You do not need to manually define this route.
Client Credentials Grant Tokens
The client credentials grant is suitable for machine-to-machine authentication. For example, you might use this grant in a scheduled job which is performing maintenance tasks over an API.
Before your application can issue tokens via the client credentials grant, you will need to create a client credentials grant client. You may do this using the --client
option of the passport:client
Artisan command:
php artisan passport:client --client
Next, to use this grant type, you need to add the CheckClientCredentials
middleware to the $routeMiddleware
property of your app/Http/Kernel.php
file:
use Laravel\Passport\Http\Middleware\CheckClientCredentials;
protected $routeMiddleware = [
'client' => CheckClientCredentials::class,
];
Then, attach the middleware to a route:
Route::get('/orders', function (Request $request) {
...
})->middleware('client');
To restrict access to the route to specific scopes, you may provide a comma-delimited list of the required scopes when attaching the client
middleware to the route:
Route::get('/orders', function (Request $request) {
...
})->middleware('client:check-status,your-scope');
Retrieving Tokens
To retrieve a token using this grant type, make a request to the oauth/token
endpoint:
use Illuminate\Support\Facades\Http;
$response = Http::asForm()->post('http://passport-app.test/oauth/token', [
'grant_type' => 'client_credentials',
'client_id' => 'client-id',
'client_secret' => 'client-secret',
'scope' => 'your-scope',
]);
return $response->json()['access_token'];
Personal Access Tokens
Sometimes, your users may want to issue access tokens to themselves without going through the typical authorization code redirect flow. Allowing users to issue tokens to themselves via your application's UI can be useful for allowing users to experiment with your API or may serve as a simpler approach to issuing access tokens in general.
Creating A Personal Access Client
Before your application can issue personal access tokens, you will need to create a personal access client. You may do this by executing the passport:client
Artisan command with the --personal
option. If you have already run the passport:install
command, you do not need to run this command:
php artisan passport:client --personal
After creating your personal access client, place the client's ID and plain-text secret value in your application's .env
file:
PASSPORT_PERSONAL_ACCESS_CLIENT_ID="client-id-value"
PASSPORT_PERSONAL_ACCESS_CLIENT_SECRET="unhashed-client-secret-value"
Managing Personal Access Tokens
Once you have created a personal access client, you may issue tokens for a given user using the createToken
method on the App\Models\User
model instance. The createToken
method accepts the name of the token as its first argument and an optional array of scopes as its second argument:
use App\Models\User;
$user = User::find(1);
// Creating a token without scopes...
$token = $user->createToken('Token Name')->accessToken;
// Creating a token with scopes...
$token = $user->createToken('My Token', ['place-orders'])->accessToken;
JSON API
Passport also includes a JSON API for managing personal access tokens. You may pair this with your own frontend to offer your users a dashboard for managing personal access tokens. Below, we'll review all of the API endpoints for managing personal access tokens. For convenience, we'll use Axios to demonstrate making HTTP requests to the endpoints.
The JSON API is guarded by the web
and auth
middleware; therefore, it may only be called from your own application. It is not able to be called from an external source.
GET /oauth/scopes
This route returns all of the scopes defined for your application. You may use this route to list the scopes a user may assign to a personal access token:
axios.get('/oauth/scopes')
.then(response => {
console.log(response.data);
});
GET /oauth/personal-access-tokens
This route returns all of the personal access tokens that the authenticated user has created. This is primarily useful for listing all of the user's tokens so that they may edit or revoke them:
axios.get('/oauth/personal-access-tokens')
.then(response => {
console.log(response.data);
});
POST /oauth/personal-access-tokens
This route creates new personal access tokens. It requires two pieces of data: the token's name
and the scopes
that should be assigned to the token:
const data = {
name: 'Token Name',
scopes: []
};
axios.post('/oauth/personal-access-tokens', data)
.then(response => {
console.log(response.data.accessToken);
})
.catch (response => {
// List errors on response...
});
DELETE /oauth/personal-access-tokens/{token-id}
This route may be used to revoke personal access tokens:
axios.delete('/oauth/personal-access-tokens/' + tokenId);
Protecting Routes
Via Middleware
Passport includes an authentication guard that will validate access tokens on incoming requests. Once you have configured the api
guard to use the passport
driver, you only need to specify the auth:api
middleware on any routes that should require a valid access token:
Route::get('/user', function () {
//
})->middleware('auth:api');
Multiple Authentication Guards
If your application authenticates different types of users that perhaps use entirely different Eloquent models, you will likely need to define a guard configuration for each user provider type in your application. This allows you to protect requests intended for specific user providers. For example, given the following guard configuration the config/auth.php
configuration file:
'api' => [
'driver' => 'passport',
'provider' => 'users',
],
'api-customers' => [
'driver' => 'passport',
'provider' => 'customers',
],
The following route will utilize the api-customers
guard, which uses the customers
user provider, to authenticate incoming requests:
Route::get('/customer', function () {
//
})->middleware('auth:api-customers');
{tip} For more information on using multiple user providers with Passport, please consult the password grant documentation.
Passing The Access Token
When calling routes that are protected by Passport, your application's API consumers should specify their access token as a Bearer
token in the Authorization
header of their request. For example, when using the Guzzle HTTP library:
use Illuminate\Support\Facades\Http;
$response = Http::withHeaders([
'Accept' => 'application/json',
'Authorization' => 'Bearer '.$accessToken,
])->get('https://passport-app.test/api/user');
return $response->json();
Token Scopes
Scopes allow your API clients to request a specific set of permissions when requesting authorization to access an account. For example, if you are building an e-commerce application, not all API consumers will need the ability to place orders. Instead, you may allow the consumers to only request authorization to access order shipment statuses. In other words, scopes allow your application's users to limit the actions a third-party application can perform on their behalf.
Defining Scopes
You may define your API's scopes using the Passport::tokensCan
method in the boot
method of your application's App\Providers\AuthServiceProvider
class. The tokensCan
method accepts an array of scope names and scope descriptions. The scope description may be anything you wish and will be displayed to users on the authorization approval screen:
/**
* Register any authentication / authorization services.
*
* @return void
*/
public function boot()
{
$this->registerPolicies();
Passport::routes();
Passport::tokensCan([
'place-orders' => 'Place orders',
'check-status' => 'Check order status',
]);
}
Default Scope
If a client does not request any specific scopes, you may configure your Passport server to attach default scope(s) to the token using the setDefaultScope
method. Typically, you should call this method from the boot
method of your application's App\Providers\AuthServiceProvider
class:
use Laravel\Passport\Passport;
Passport::tokensCan([
'place-orders' => 'Place orders',
'check-status' => 'Check order status',
]);
Passport::setDefaultScope([
'check-status',
'place-orders',
]);
Assigning Scopes To Tokens
When Requesting Authorization Codes
When requesting an access token using the authorization code grant, consumers should specify their desired scopes as the scope
query string parameter. The scope
parameter should be a space-delimited list of scopes:
Route::get('/redirect', function () {
$query = http_build_query([
'client_id' => 'client-id',
'redirect_uri' => 'http://example.com/callback',
'response_type' => 'code',
'scope' => 'place-orders check-status',
]);
return redirect('http://passport-app.test/oauth/authorize?'.$query);
});
When Issuing Personal Access Tokens
If you are issuing personal access tokens using the App\Models\User
model's createToken
method, you may pass the array of desired scopes as the second argument to the method:
$token = $user->createToken('My Token', ['place-orders'])->accessToken;
Checking Scopes
Passport includes two middleware that may be used to verify that an incoming request is authenticated with a token that has been granted a given scope. To get started, add the following middleware to the $routeMiddleware
property of your app/Http/Kernel.php
file:
'scopes' => \Laravel\Passport\Http\Middleware\CheckScopes::class,
'scope' => \Laravel\Passport\Http\Middleware\CheckForAnyScope::class,
Check For All Scopes
The scopes
middleware may be assigned to a route to verify that the incoming request's access token has all of the listed scopes:
Route::get('/orders', function () {
// Access token has both "check-status" and "place-orders" scopes...
})->middleware(['auth:api', 'scopes:check-status,place-orders']);
Check For Any Scopes
The scope
middleware may be assigned to a route to verify that the incoming request's access token has at least one of the listed scopes:
Route::get('/orders', function () {
// Access token has either "check-status" or "place-orders" scope...
})->middleware(['auth:api', 'scope:check-status,place-orders']);
Checking Scopes On A Token Instance
Once an access token authenticated request has entered your application, you may still check if the token has a given scope using the tokenCan
method on the authenticated App\Models\User
instance:
use Illuminate\Http\Request;
Route::get('/orders', function (Request $request) {
if ($request->user()->tokenCan('place-orders')) {
//
}
});
Additional Scope Methods
The scopeIds
method will return an array of all defined IDs / names:
use Laravel\Passport\Passport;
Passport::scopeIds();
The scopes
method will return an array of all defined scopes as instances of Laravel\Passport\Scope
:
Passport::scopes();
The scopesFor
method will return an array of Laravel\Passport\Scope
instances matching the given IDs / names:
Passport::scopesFor(['place-orders', 'check-status']);
You may determine if a given scope has been defined using the hasScope
method:
Passport::hasScope('place-orders');
Consuming Your API With JavaScript
When building an API, it can be extremely useful to be able to consume your own API from your JavaScript application. This approach to API development allows your own application to consume the same API that you are sharing with the world. The same API may be consumed by your web application, mobile applications, third-party applications, and any SDKs that you may publish on various package managers.
Typically, if you want to consume your API from your JavaScript application, you would need to manually send an access token to the application and pass it with each request to your application. However, Passport includes a middleware that can handle this for you. All you need to do is add the CreateFreshApiToken
middleware to your web
middleware group in your app/Http/Kernel.php
file:
'web' => [
// Other middleware...
\Laravel\Passport\Http\Middleware\CreateFreshApiToken::class,
],
{note} You should ensure that the
CreateFreshApiToken
middleware is the last middleware listed in your middleware stack.
This middleware will attach a laravel_token
cookie to your outgoing responses. This cookie contains an encrypted JWT that Passport will use to authenticate API requests from your JavaScript application. The JWT has a lifetime equal to your session.lifetime
configuration value. Now, since the browser will automatically send the cookie with all subsequent requests, you may make requests to your application's API without explicitly passing an access token:
axios.get('/api/user')
.then(response => {
console.log(response.data);
});
Customizing The Cookie Name
If needed, you can customize the laravel_token
cookie's name using the Passport::cookie
method. Typically, this method should be called from the boot
method of your application's App\Providers\AuthServiceProvider
class:
/**
* Register any authentication / authorization services.
*
* @return void
*/
public function boot()
{
$this->registerPolicies();
Passport::routes();
Passport::cookie('custom_name');
}
CSRF Protection
When using this method of authentication, you will need to ensure a valid CSRF token header is included in your requests. The default Laravel JavaScript scaffolding includes an Axios instance, which will automatically use the encrypted XSRF-TOKEN
cookie value to send an X-XSRF-TOKEN
header on same-origin requests.
{tip} If you choose to send the
X-CSRF-TOKEN
header instead ofX-XSRF-TOKEN
, you will need to use the unencrypted token provided bycsrf_token()
.
Events
Passport raises events when issuing access tokens and refresh tokens. You may use these events to prune or revoke other access tokens in your database. If you would like, you may attach listeners to these events in your application's App\Providers\EventServiceProvider
class:
/**
* The event listener mappings for the application.
*
* @var array
*/
protected $listen = [
'Laravel\Passport\Events\AccessTokenCreated' => [
'App\Listeners\RevokeOldTokens',
],
'Laravel\Passport\Events\RefreshTokenCreated' => [
'App\Listeners\PruneOldTokens',
],
];
Testing
Passport's actingAs
method may be used to specify the currently authenticated user as well as its scopes. The first argument given to the actingAs
method is the user instance and the second is an array of scopes that should be granted to the user's token:
use App\Models\User;
use Laravel\Passport\Passport;
public function test_servers_can_be_created()
{
Passport::actingAs(
User::factory()->create(),
['create-servers']
);
$response = $this->post('/api/create-server');
$response->assertStatus(201);
}
Passport's actingAsClient
method may be used to specify the currently authenticated client as well as its scopes. The first argument given to the actingAsClient
method is the client instance and the second is an array of scopes that should be granted to the client's token:
use Laravel\Passport\Client;
use Laravel\Passport\Passport;
public function test_orders_can_be_retrieved()
{
Passport::actingAsClient(
Client::factory()->create(),
['check-status']
);
$response = $this->get('/api/orders');
$response->assertStatus(200);
}
