Laravel Authentication Tutorial: A Comprehensive Guide


Laravel Authentication Tutorial: A Comprehensive Guide

Laravel, known for its elegant syntax and powerful features, simplifies the development of web applications. In this Laravel Authentication Tutorial, we’ll walk through a step-by-step example of implementing user login functionality in a Laravel application. By the end of this tutorial, you’ll have a solid understanding of Laravel’s authentication system and how to create a secure and user-friendly login system for your web projects.

1. Introduction

Authentication is critical to web applications, ensuring that only authorized users can access certain resources. Laravel provides a robust authentication system out of the box, making it easier for developers to implement secure user login functionality.

2. Setting Up a Laravel Project

If you haven’t installed Laravel yet, you can do so by using Composer:

composer create-project --prefer-dist laravel/laravel your-project-name

Navigate to your project directory:

cd your-project-name

3. Database Configuration

Configure your database settings in the .env file. Set the DB_CONNECTION, DB_HOST, DB_PORT, DB_DATABASE, DB_USERNAME, and DB_PASSWORD variables according to your database setup.

4. User Model and Migration (Optional)

Generate the User model and migration using the Artisan command (In the latest Laravel Version it does not require to create User Model, as it has already been created while creating the Laravel Project):

php artisan make:model User -m

This command creates a User model and its corresponding migration file. Run the migration to create the users table in the database:

php artisan migrate

5. Laravel Authentication Scaffolding

Laravel provides a convenient Artisan command to generate the basic scaffolding for authentication:

php artisan make:auth

This command generates the necessary controllers, views, and routes for user registration and login.

6. Customizing the User Login Process

To customize the user login process, we can leverage Laravel’s built-in authentication controllers. Open the LoginController.php file in the app/Http/Controllers/Auth directory. Customize the login method to suit your needs.

// app/Http/Controllers/Auth/LoginController.php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class LoginController extends Controller
    use AuthenticatesUsers;

    protected $redirectTo = '/home';

    public function __construct()

    protected function authenticated(Request $request, $user)
        // Custom logic after a successful login
        // For example, you might want to redirect users based on their role
        if ($user->isAdmin()) {
            return redirect('/admin/dashboard');
        } else {
            return redirect('/user/dashboard');

    protected function credentials(Request $request)
        return $request->only($this->username(), 'password');

    protected function sendLoginResponse(Request $request)

        return $this->authenticated($request, Auth::user())
            ?: redirect()->intended($this->redirectPath());

    protected function sendFailedLoginResponse(Request $request)
        throw ValidationException::withMessages([
            $this->username() => [trans('auth.failed')],

    protected function username()
        return 'email';

    public function logout(Request $request)



        return redirect('/');

7. Adding Middleware for Authentication

Middleware in Laravel provides a mechanism to filter HTTP requests. Laravel’s authentication middleware ensures that only authenticated users can access specific routes. Open the app/Http/Kernel.php file and add the auth middleware to the $routeMiddleware array:

// app/Http/Kernel.php

protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,

8. Creating Login Views

Laravel’s authentication scaffolding already includes login views, but you can customize them as needed. Find the login views in the resources/views/auth directory. Adjust the login.blade.php file to match your application’s design and requirements.

// resources/views/auth/login.blade.php
<!-- Customize the login view based on your application's design -->

9. Handling User Authentication in Controllers

Create controllers to handle the user authentication logic. You can customize the controllers generated by the authentication scaffolding or create new ones. Use the Auth facade to interact with the authentication system.

// Sample controller method for user login

use Illuminate\Support\Facades\Auth;


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

    if (Auth::attempt($credentials)) {
        // Authentication passed
        return redirect()->intended('/dashboard');

    // Authentication failed
    return back()->withErrors(['email' => 'Invalid credentials']);

10. Testing the User Login Functionality

Test the user login functionality by visiting the login page, entering valid credentials, and ensuring successful authentication. Laravel’s testing tools make it easy to write automated tests for your authentication flow.

11. Additional Features and Best Practices

Consider implementing features like password reset, account lockout, and two-factor authentication for enhanced security. Follow best practices, such as storing passwords securely using Laravel’s built-in hashing mechanisms.


In this comprehensive Laravel Authentication Tutorial, we’ve covered the entire process of implementing user login functionality in a Laravel application. From project setup to customizing views and controllers, you now have a solid foundation for creating secure and user-friendly authentication systems in your Laravel projects. As you continue to explore Laravel’s capabilities, remember to consult the official documentation for the latest features and best practices. Happy coding!
