In Laravel, the process of user authentication is a crucial aspect when developing a project. User authentication becomes particularly essential in applications where user registration is required. This ensures that each user can access their personalized information.

For instance, consider a banking application where user registration is a necessary step. Users need to sign up with their email and password, allowing them to log in securely and view their account balance and transactions. Laravel simplifies the implementation of this authentication process, making it efficient and secure.

The typical steps involved in setting up user authentication in Laravel include:

Installation of Laravel Authentication System:

Laravel provides a built-in authentication system that can be easily installed using Artisan commands.

To set up authentication scaffolding in a Laravel web application, you can use the Laravel UI package. Depending on your preferred frontend technology, you can choose from Bootstrap, Vue.js, or React.js. Follow the instructions below:

For Bootstrap:

Install the Laravel UI package:

composer require laravel/ui

Generate Bootstrap views with authentication scaffolding:

php artisan ui bootstrap --auth

For Vue.js:

Install the Laravel UI package:

composer require laravel/ui

Generate Vue.js views with authentication scaffolding:

php artisan ui vue –auth

For React.js:

Install the Laravel UI package:

composer require laravel/ui

Generate React.js views with authentication scaffolding:

php artisan ui react –auth

These commands will set up the necessary files and views for user authentication based on your chosen frontend technology. Make sure to run npm install and npm run dev after executing the above commands to compile the assets.

Database Migration:

Run the migration command to create the necessary tables in the database for user authentication:

php artisan migrate

User Model:

Laravel uses the User model by default for authentication. Ensure that your User model extends the Illuminate\Foundation\Auth\User class.

Routes:

Laravel creates authentication routes in the web.php file. These routes include registration, login, and password reset routes. You can customize these routes based on your project's requirements.

Views:

The authentication scaffolding also generates views for registration and login forms, which can be found in the resources/views/auth directory. You can customize views to match your application’s design.

Controller:

Laravel creates controllers for handling authentication logic. The RegisterController and LoginController are responsible for user registration and login, respectively.

Middleware:

Laravel includes middleware for protecting routes that require authentication. The auth middleware can be applied to routes to ensure that only authenticated users can access them.

Blade Directives:

Laravel's Blade templating engine provides directives like @auth and @guest to conditionally show content based on the user's authentication status.

Authentication Facade:

Laravel provides the Auth facade, which allows you to interact with the authentication system. You can use methods like attempt for login attempts, user to retrieve the authenticated user, and check to check if a user is authenticated.

Logout:

To implement user logout, Laravel includes the LogoutController and a corresponding route. You can customize the behavior of logout if needed.

If you want to create custom login, registration, or logout functionality in Laravel, you'll need to build your own custom functions. Below is an example to help you understand how to implement these custom features:

How to create custom Laravel authentication process:

We will use the same User model, but we will create our own custom controller to create a controller run the below command.

php artisan make:controller CustomAuthController
// app/Http/Controllers/CustomAuthController.php



use App\Http\Controllers\Controller;

use App\Models\User;

use Illuminate\Http\Request;

use Illuminate\Support\Facades\Hash;



class CustomAuthController extends Controller

{

public function showRegistrationForm()

{

return view('auth.register');

}



public function register(Request $request)

{

// Your custom registration logic here

$validatedData = $request->validate([

'name' => 'required|string|max:255',

'email' => 'required|string|email|max:255|unique:users',

'password' => 'required|string|min:8|confirmed',

]);



$user = User::create([

'name' => $validatedData['name'],

'email' => $validatedData['email'],

'password' => Hash::make($validatedData['password']),

]);



// Log in the user after registration if needed



return redirect('/dashboard'); // Adjust the redirect path as needed

}

}



public function showLoginForm()

{

return view('auth.login');

}



public function login(Request $request)

{

// Your custom login logic here

$credentials = $request->validate([

'email' => 'required|email',

'password' => 'required',

]);



if (auth()->attempt($credentials)) {

// Authentication passed

return redirect('/dashboard'); // Adjust the redirect path as needed

}



// Authentication failed

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

}





public function logout()

{

auth()->logout();



// Your custom logout logic here, if needed



return redirect('/'); // Adjust the redirect path as needed

}

Create a Custom Login Form:

You need to create a login form in resources/views/auth/custom-login.blade.php in this directory To create a login form in the resources/views/auth/custom-login.blade.php file, you can use the following example as a starting point. This is a basic HTML form that you can customize based on your project's design:

<form method="POST" action="{{ route('custom.login') }}">

@csrf



<div>

<label for="email">Email</label>

<input type="email" name="email" id="email" required autofocus />

</div>



<div>

<label for="password">Password</label>

<input type="password" name="password" id="password" required />

</div>



<div>

<button type="submit">Login</button>

</div>

</form>
  1. The form has the POST method and its action is set to the route named custom.login. Make sure to define this route in your web.php file.
  2. @csrf is used to generate a CSRF token for the form.
  3. There are input fields for the email and password.
  4. The submit button triggers the login process.

Below is a basic example of a registration form design using HTML. You can use this as a starting point and customize it according to your project's design:

<!DOCTYPE html>

<html lang="en">

<head>

<meta charset="UTF-8">

<meta name="viewport" content="width=device-width, initial-scale=1.0">

<title>Registration</title>

</head>

<body>



<form method="POST" action="{{ route('custom.register') }}">

@csrf



<label for="name">Name:</label>

<input type="text" name="name" id="name" required>

<br>



<label for="email">Email:</label>

<input type="email" name="email" id="email" required>

<br>



<label for="password">Password:</label>

<input type="password" name="password" id="password" required>

<br>



<label for="password_confirmation">Confirm Password:</label>

<input type="password" name="password_confirmation" id="password_confirmation" required>

<br>



<button type="submit">Register</button>

</form>



</body>

</html>
  1. The form has the POST method and its action is set to the route named custom.register. Make sure to define this route in your web.php file.
  2. @csrf is used to generate a CSRF token for the form.
  3. There are input fields for the user's name, email, password, and password confirmation.
  4. The submit button triggers the registration process.

Conclusion:
