How to Implement Laravel Passport Login in Your App

Laravel Passport is a Laravel package that provides a simple and secure way to implement OAuth 2.0 authentication in your application. OAuth 2.0 is a popular authorization framework that allows users to grant third-party applications access to their protected resources without having to share their passwords.

There are many benefits to using Laravel Passport for authentication, including:

• It is easy to use. Laravel Passport provides a simple API that makes it easy to implement OAuth 2.0 authentication in your application.
• It is secure. Laravel Passport uses industry-standard security practices to protect your users’ credentials.
• It is scalable. Laravel Passport is designed to scale to meet the needs of even the most demanding applications.

Requirements for Laravel Passport

To implement Laravel Passport login, you will need the following:

• Laravel 8 or higher
• Composer

Installation

To install Laravel Passport, you can run the following command:

composer require laravel/passport

This will install the Laravel Passport package and its dependencies.

Configuration

Once Laravel Passport is installed, you will need to configure it in your config/auth.php file. In the guards section, add the following:

'api' => [
    'driver' => 'passport',
],

This tells Laravel that the api guard will use Laravel Passport for authentication.

Creating a user model

Laravel Passport needs a user model to store the users’ credentials. You can create a user model by running the following command:

php artisan make:model User -m

This will create a new User model and a migration file.

Open the User model and extend the Laravel\Passport\AuthModel class. This will allow Laravel Passport to interact with your user model.

Creating a login endpoint

Laravel Passport provides a login endpoint that you can use to authenticate users. To create this endpoint, you can create a controller that extends the Laravel\Passport\Http\Controllers\AuthController class.

In your controller, add the following method:

public function login(Request $request)
{
    $credentials = $request->only('email', 'password');

    if (Auth::attempt($credentials)) {
        return $this->respondWithToken(Auth::user()->createToken());
    }

    return response()->json(['error' => 'Unauthorized'], 401);
}

This method will authenticate the user and return an access token if the credentials are valid. Have you ever get stucked in Laravel Development ? Contact me for Free

Creating a register endpoint

Laravel Passport also provides a register endpoint that you can use to register new users. To create this endpoint, you can create a controller that extends the Laravel\Passport\Http\Controllers\AuthController class.

In your controller, add the following method:

public function register(Request $request)
{
    $this->validate($request, [
        'name' => 'required|string',
        'email' => 'required|email|unique:users',
        'password' => 'required|string|min:6',
    ]);

    $user = User::create([
        'name' => $request->input('name'),
        'email' => $request->input('email'),
        'password' => bcrypt($request->input('password')),
    ]);

    return $this->respondWithToken($user->createToken());
}

This method will register a new user and return an access token.

Testing

Once you have implemented Laravel Passport login, you can test it by running the following commands:

php artisan make:test PassportTest
php artisan test

This will create a new test class and run the tests.
