Implementing authentication in Laravel is a straightforward process thanks to Laravel’s built-in authentication system. Here is a step-by-step guide to help you set up authentication in a Laravel application:

1. Setting Up a New Laravel Project

First, create a new Laravel project using Composer. Open your terminal and run:

composer create-project --prefer-dist laravel/laravel blog

Navigate to your project directory:

cd blog

2. Setting Up the Database

Configure your database settings in the .env file. Update the following lines with your database details:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your_database_name
DB_USERNAME=your_database_username
DB_PASSWORD=your_database_password

Run the migrations to create the necessary tables for authentication:

php artisan migrate

3. Installing Laravel Breeze (Optional)

Laravel Breeze is a simple and minimal implementation of all of Laravel’s authentication features, including login, registration, password reset, email verification, and password confirmation. To install it, run:

composer require laravel/breeze --dev

Then install Breeze and run the migrations:

php artisan breeze:install
npm install && npm run dev
php artisan migrate

4. Setting Up Authentication Manually (Optional)

If you prefer not to use Laravel Breeze, you can manually set up authentication. Laravel provides built-in controllers and views for authentication.

Creating Controllers and Views

Generate the authentication controllers and views using the following Artisan command:

php artisan make:auth

Updating Routes

Open the routes/web.php file and ensure the authentication routes are registered:

Auth::routes();

Middleware

Laravel provides middleware to restrict access to certain routes. You can apply this middleware to your routes or controllers to ensure only authenticated users can access them. For example:

Route::get('/home', [App\Http\Controllers\HomeController::class, 'index'])->middleware('auth');

5. Customizing Authentication

You can customize the authentication logic by modifying the generated controllers located in the app/Http/Controllers/Auth directory. For instance, to customize the login behavior, edit the LoginController.

6. Protecting Routes

To protect routes, use the auth middleware. For example, to protect a route so only authenticated users can access it:

Route::get('/dashboard', function () {
    return view('dashboard');
})->middleware('auth');

7. Testing Authentication

Start the Laravel development server to test the authentication system:

php artisan serve

Navigate to http://localhost:8000 in your browser. You should see the login and registration pages. Register a new user and log in to test the authentication flow.

Conclusion

By following these steps, you can set up a robust authentication system in your Laravel application. Whether you use Laravel Breeze for a quick setup or configure authentication manually, Laravel’s built-in features make it easy to secure your application and manage user authentication.
