What is Authentication in Laravel?

Authentication in Laravel is the process of verifying a user’s identity — usually by checking a username/email and password — to control access to protected parts of a web application.

Key Points:

  • Laravel provides built-in authentication features to make it quick and secure.
  • It includes login, registration, password reset, and email verification functionalities.
  • Authentication ensures that only authorized users can access certain routes, controllers, or data.

 

How Laravel Handles Authentication:

Laravel provides two main ways to implement authentication:

1. Starter Kit (Laravel Breeze, Jetstream, or Fortify)

You can install packages that scaffold full authentication features.

Example using Laravel Breeze:

Put this comment in your project terminal:


composer require laravel/breeze --dev
php artisan breeze:install
npm install && npm run dev
php artisan migrate

Then go to browser:


http://localhost:8000/register
http://localhost:8000/login

2. Manual Authentication (Custom)

You can create custom login systems using:

  • Auth facade
  • Middleware (auth)
  • LoginController, RegisterController
  • bcrypt() for password hashing

Example Login Logic:

LoginController


if (Auth::attempt(['email' => $email, 'password' => $password])) {
    return redirect()->intended('dashboard');
}

Auth Middleware

To protect routes:

routes/web.php:


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

Authentication Files Location

  • Controllers: app/Http/Controllers/Auth/
  • Views (with Breeze): resources/views/auth/
  • Config: config/auth.php
  • Middleware: app/Http/Middleware/Authenticate.php
