Laravel 8 REST API Authentication with JWT

Hello Dev.

In this articles, we’ll be gaining knowledge of authenticate REST APIs using JWT in the latest Laravel 8 version. you may educated ways to create a REST API the usage of Laravel 8 with JWT authentication.

We will see the way to set up JWT authentication in Laravel 8 and implement a secured REST API using the tymon/jwt-auth package.

in this academic, we’ll see one by one implement a REST API with php and Laravel 8 with authentication via JWT tokens.

Step 1: Install Laravel 8 Application

permit’s begin our instance by create a Laravel 8 application the use of Composer — the dependency management tool for php developers.

Head over to a new command-line interface and run the following command:

$ composer create-project --prefer-dist laravel/laravel jwtdemo

Step 2: Configuring a MySQL Database

After creating your Laravel 8 application using Composer, let’s configure a MySQL database in second step.

Open the .env file located in the root of your Laravel 8′ application. Next, add the following database configuration details:

DB_DATABASE= <database-name>
DB_USERNAME= <database-username>
DB_PASSWORD= <database-password>

Step 3: Install jwt

Now that we have a Laravel 8 application with a MySQL database configured, let’s start implementing JWT authentication by installing the jwt-auth package.

Head back to your terminal and run the following command from the root of your project’s folder:

$ composer require tymon/jwt-auth

Step 4: Set up JWT Authentication

in this step, we have a Laravel 8 application with MySQL configured. We also installed the jwt-auth library in the previous step. Now, let’s set up JWT authentication in our application.

go to the config/app.php file and add JWT providers and aliases as follows:

'providers' => [
'aliases' => [
'JWTAuth' => 'TymonJWTAuthFacadesJWTAuth',
'JWTFactory' => 'TymonJWTAuthFacadesJWTFactory',

Next, go to your terminal and run the following command:

$ php artisan vendor:publish --provider="TymonJWTAuthProvidersJWTAuthServiceProvider"

Step 5: Generat JWT Secret Key

After configuring JWT authentication in our Laravel 8 app. We’ll need to generate a JWT secret key in this step.

Head over to your terminal and run the following command to generate the JWT secret key:

$ php artisan jwt:generate

Next, open the vendor/tymon/src/Commands/JWTGenerateCommand.php and update it as follows:

public function handle() {$this->fire();}

Step 6: Implement JWT Authentication

After configuring JWT in Laravel 8. In this step, we’ll implement it in the User model.

Open the App/User.php file, and update it as follows:


namespace App;

use IlluminateNotificationsNotifiable;
use IlluminateFoundationAuthUser as Authenticatable;

class User extends Authenticatable
    use Notifiable;

    protected $fillable = [
        'name', 'email', 'password',

    protected $hidden = [
        'password', 'remember_token',


Step 7: Implement the REST API Controller

Let’s now implement a Laravel 8 controller for handling JWT authentication in our REST API application.

Head back to your terminal and run the following command to generate a controller:

$ php artisan make:controller JwtAuthController

Next, open the app/http/controllers/JwtAuthController.php file, and add the following methods:



namespace AppHttpControllers;

use JWTAuth;
use Validator;
use AppUser;
use IlluminateHttpRequest;
use AppHttpRequestsRegisterAuthRequest;
use TymonJWTAuthExceptionsJWTException;
use SymfonyComponentHttpFoundationResponse;

class JwtAuthController extends Controller
    public $token = true;

    public function register(Request $request)

         $validator = Validator::make($request->all(), 
                      'name' => 'required',
                      'email' => 'required|email',
                      'password' => 'required',  
                      'c_password' => 'required|same:password', 

         if ($validator->fails()) {  

              return response()->json(['error'=>$validator->errors()], 401); 

        $user = new User();
        $user->name = $request->name;
        $user->email = $request->email;
        $user->password = bcrypt($request->password);

        if ($this->token) {
            return $this->login($request);

        return response()->json([
            'success' => true,
            'data' => $user
        ], Response::HTTP_OK);

    public function login(Request $request)
        $input = $request->only('email', 'password');
        $jwt_token = null;

        if (!$jwt_token = JWTAuth::attempt($input)) {
            return response()->json([
                'success' => false,
                'message' => 'Invalid Email or Password',
            ], Response::HTTP_UNAUTHORIZED);

        return response()->json([
            'success' => true,
            'token' => $jwt_token,

    public function logout(Request $request)
        $this->validate($request, [
            'token' => 'required'

        try {

            return response()->json([
                'success' => true,
                'message' => 'User logged out successfully'
        } catch (JWTException $exception) {
            return response()->json([
                'success' => false,
                'message' => 'Sorry, the user cannot be logged out'
            ], Response::HTTP_INTERNAL_SERVER_ERROR);

    public function getUser(Request $request)
        $this->validate($request, [
            'token' => 'required'

        $user = JWTAuth::authenticate($request->token);

        return response()->json(['user' => $user]);

Step 8: Add REST API Routes

Now that we have implemented JWT authentication in our Laravel 8 User model. In this step, we’ll proceed to create our REST API routes.

Open the routes/api.php file, and add code as below:

Route::post('login', 'JwtAuthController@login');
Route::post('register', 'JwtAuthController@register');

Route::group(['middleware' => 'auth.jwt'], function () {

    Route::get('logout', 'JwtAuthController@logout');
    Route::get('user-info', 'JwtAuthController@getUser');

Step 9: Run Application

Now we are prepared to run our JWT authentication in Laravel 8 REST API application instance, so run bellow command for brief run:

$ php artisan serve
