Getting Started with Laravel Passport Authentication

July 14, 2021

Most systems nowadays require authentications to access resources. For example, user login or API resource access. In this tutorial, we will discuss the Laravel Passport package to authenticate your application APIs. The task includes the creation and validation of tokens.


By the end of this tutorial, you should be able to create your Laravel application APIs and secure them using the Laravel passport package.

Table of contents


To follow this article along, the reader should have the following:

  • Laravel 8 application installed in your development environment. Basic knowledge in Laravel is required to follow this post along.
  • Postman application to test our application
  • RESTful APIs. You should be familiar with GET, PUT, POST, CREATE, DELETE operations.

Installing the ‘passport’ package

To install this package to your running application, run the following commands:

It’s important to note that this is not an introduction to Laravel tutorial, for that you can refer to this Laravel beginner article to learn more about Laravel installation.

cd api-authentication-app

composer require laravel/passport


  - Installing league/event (2.2.0): Downloading (100%)

----------------------------------------------- # omitted installations

Preparing passport

Passport comes with the database setup to store its access tokens and 0Auth2 client activities. We should therefore run our migrations as follows to create tables:

php artisan migrate


# This command generates tables for passport auth plus default Laravel tables
Migration table created successfully.
Migrating: 2014_10_12_000000_create_users_table
Migrated:  2014_10_12_000000_create_users_table (99.77ms)
----------------------------------- # omitted tables

Migrated:  2016_06_01_000005_create_oauth_personal_access_clients_table (85.12ms)
---------------------------------------- # omitted tables

Now that we jave our passport authentication tables, we need to set up encryption keys that we’ll use in the application to generate secure access tokens.

php artisan passport:install


# this command generates the encryption keys, personal access client, and password
# grant client which we'll use to generate the access tokens
Encryption keys generated successfully.
Personal access client created successfully.
Client ID: 1
# your client id 1 will be different from the output below
Client secret: KTIqQ7nwiIoJf9uxxxxxxxxxxxxxxxxxxxxxxxx
Password grant client created successfully.
Client ID: 2
# your client id 2 will be different from the output below
Client secret: 43x92qhcW4Itxxxxxxxxxxxxxxxxxxxxxxxxx

Setting up models to use passport / Passport configurations

We’re performing these configurations on the User model to help us access user tokens. We’ll therefore have the ability to authenticate them.

We’ll therefore add the Laravel\Passport\HasApiTokens trait to our Laravel generated User Model(App/Models/User).


namespace App\Models;

use Laravel\Passport\HasApiTokens;

class User extends Authenticatable
    use HasApiTokens, HasFactory, Notifiable;
    // our user table columns
    protected $fillable = [

    protected $hidden = [

Next, update the App\Providers\AuthServiceProvider as follows:


use Laravel\Passport\Passport;

class AuthServiceProvider extends ServiceProvider
    protected $policies = [
        'App\Models\Model' => 'App\Policies\ModelPolicy',

     * we call the passport: routes 
     * to register routes that our application will use * to issue tokens and clients
     * @return void
    public function boot()
        // call passport:routes() here
        if (! $this->app->routesAreCached()) {

Now that we’ve got a way to register tokens routes, let’s update the config/auth.php as follows:


return [
* update the guards api only
    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',

        * update the driver from token to passport
        'api' => [
            'driver' => 'passport',
            'provider' => 'users',
            'hash' => false,


Add authentication controller

Now that we’re all set with passport configurations, let’s create an authentication controller.

php artisan make:controller passportAuthController

Update this controller as follows:

class passportAuthController extends Controller
     * handle user registration request
    public function registerUserExample(Request $request){
        $user= User::create([
            'name' =>$request->name,

        $access_token_example = $user->createToken('')->access_token;
        //return the access token we generated in the above step
        return response()->json(['token'=>$access_token_example],200);

     * login user to our application
    public function loginUserExample(Request $request){
            //generate the token for the user
            $user_login_token= auth()->user()->createToken('')->accessToken;
            //now return this token on success login attempt
            return response()->json(['token' => $user_login_token], 200);
            //wrong login credentials, return, user not authorised to our system, return error code 401
            return response()->json(['error' => 'UnAuthorised Access'], 401);

     * This method returns authenticated user details
    public function authenticatedUserDetails(){
        //returns details
        return response()->json(['authenticated-user' => auth()->user()], 200);

Remember to read the above controller comments to understand the code.

Add application authentication routes

With the controller ready to handle Requests, let’s add the routes to finish up the application setup.

//add this middleware to ensure that every request is authenticated
    Route::get('user', [passportAuthController::class,'authenticatedUserDetails']);

Testing our passport application

Serve your application by running the following command:

# sever starts on port 8000 by default
php artisan serve

Now, use postman or any other tool to test your application.

Login Output:



In this tutorial, we discussed Laravel passport package. We have seen how we can configure this package in a Laravel application to generate API access tokens.

I’ve tried to take you through each process of implementing a POST and GET methods i.e. user authentication example, you can now build on this to design secure applications using Laravel passport.

Full tutorial code can be found here on the Github repository.

Happy coding!
