Laravel Passport
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.
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
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 the uuids
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));
}
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/ \{#put-oauthclientsclient-id}{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/ \{#delete-oauthclientsclient-id}{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);
});
Remember, the /oauth/authorize
route is already defined by the Passport::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.
Like the /oauth/authorize
route, the /oauth/token
route is defined for you by the Passport::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);
});
