How to Make Custom Authentication on Laravel?

To create custom authentication in Laravel, you will need to customize the default authentication functionality provided by the framework. This process involves modifying the authentication logic, controllers, and views to suit your specific requirements.

1. Create a custom authentication guard: You can create a new guard in the config/auth.php configuration file and define the corresponding user provider and model.
2. Customize authentication logic: You can implement custom authentication logic by extending or overriding the default authentication classes such as Authenticate, RedirectIfAuthenticated, and LoginController.
3. Create custom routes and controllers: Define custom routes for login, registration, and other authentication actions in your routes/web.php file. You can also create custom controllers to handle these actions.
4. Modify authentication views: Customize the authentication views such as login, registration, and password reset forms to match the design of your application.
5. Implement additional features: You can add extra features such as email verification, two-factor authentication, social login, and role-based access control to enhance the security and functionality of your authentication system.

By following these steps, you can create a custom authentication system in Laravel that meets the specific requirements of your application.

How to add email verification to custom authentication on Laravel?

To add email verification to custom authentication in Laravel, you can follow these steps:

1. Create a new migration to add a verified column to your user table. Run the following command in your terminal:

1

php artisan make:migration add_verified_to_users_table

1. In the newly created migration file, add the following code to add the verified column to the users table:

1
2
3
4
5
6

public function up()
{
    Schema::table('users', function (Blueprint $table) {
        $table->boolean('verified')->default(false);
    });
}

1. Run the migration to update your database schema with the changes:

1

php artisan migrate

1. Make sure your custom authentication logic is set up in your Laravel application. This typically involves creating custom routes, controllers, and views for registration, login, and other authentication tasks.
2. Update your registration logic to send a verification email to new users upon registration. You can do this by adding the following code in your registration controller:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

use Illuminate\Support\Facades\Mail;
use App\Mail\VerifyEmail;

$user = User::create([
    'name' => $data['name'],
    'email' => $data['email'],
    'password' => Hash::make($data['password']),
]);

Mail::to($user->email)->send(new VerifyEmail($user));

1. Create a Mailable class for the verification email. Run the following command in your terminal to generate a new Mailable class:

1

php artisan make:mail VerifyEmail --markdown=emails.verify_email

1. In the VerifyEmail Mailable class, you can customize the email content and include a verification link that will set the user's verified field to true when clicked.
2. Update your authentication logic to check if the user is verified before allowing them to log in. You can do this by adding the following check in your login controller:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

if (!auth()->attempt($credentials)) {
    return back()->withErrors(['email' => 'The provided credentials are invalid.']);
}

if (!auth()->user()->verified) {
    auth()->logout();
    return redirect()->route('verification.notice');
}

return redirect()->intended('/');

1. Create a route and view for users to verify their email address. You can create a new route that points to a verification controller method and a view that displays a message confirming the verification.
2. Finally, update your verification logic to set the verified field to true when the user clicks on the verification link in their email. You can do this by adding a verification controller method that updates the user's verified field and redirects them to a confirmation view.

By following these steps, you can add email verification to custom authentication in Laravel and ensure that only verified users are able to log in to your application.

What is multi-factor authentication in Laravel?

Multi-factor authentication (MFA) in Laravel is a security feature that requires users to provide more than one form of identification before gaining access to a system or application. This typically involves combining something the user knows (such as a password) with something they have (such as a mobile device or security key) to verify their identity. In Laravel, MFA can be implemented using packages like Laravel Multi-Factor Authentication or Laravel Two Factor Authentication to add an extra layer of security to user authentication processes.

What is token-based authentication in Laravel?

Token-based authentication in Laravel is a method of authenticating users by generating and validating a token instead of using traditional session-based authentication. This token is typically passed along with each request from the client to the server and is validated by the server to determine the identity of the user.

In Laravel, token-based authentication is commonly implemented using JSON Web Tokens (JWT) or Laravel Passport. JWT is a compact, URL-safe means of representing claims to be transferred between two parties. Laravel Passport is an OAuth2 server implementation that provides a full OAuth2 server implementation for the Laravel framework.

Token-based authentication provides a more secure and scalable way of authenticating users, particularly in APIs and stateless applications. It eliminates the need to store session data on the server-side and enables users to remain authenticated across multiple requests without the need to log in each time.

How to implement role-based authentication in Laravel?

Role-based authentication in Laravel can be implemented by following these steps:

1. Define roles: You need to define the roles that will be used in your application. This can be done by creating a Role model and a roles table in your database. Each role should have a name and a description.
2. Assign roles to users: You can assign roles to users by creating a many-to-many relationship between the User and Role models. This can be done using Laravel's Eloquent ORM. You can create a pivot table to store the relationships between users and roles.
3. Check roles in middleware: You can create a middleware that checks if the current user has the required role to access a specific route. You can define the logic for checking roles in this middleware and apply it to the routes that require role-based authentication.
4. Protect routes: You can protect your routes by applying the middleware that checks roles. You can do this by adding the middleware to the route definition in your routes/web.php file.

Example:

1

Route::get('/admin/dashboard', 'AdminController@dashboard')->middleware('role:admin');

1. Check roles in controllers: You can also check roles in your controllers by using the Auth facade provided by Laravel. You can get the currently authenticated user and check if they have the required role.

Example:

1
2
3
4
5

use Illuminate\Support\Facades\Auth;

if(Auth::user()->hasRole('admin')) {
    // Perform actions for admin users
}

By following these steps, you can implement role-based authentication in your Laravel application. This will allow you to restrict access to certain parts of your application based on the roles assigned to users.

How to handle user permissions in custom authentication on Laravel?

In Laravel, you can handle user permissions in custom authentication by following these steps:

1. Define user roles and permissions: Create a table in your database to store user roles and permissions. You can define different roles such as admin, editor, and viewer, and assign corresponding permissions to each role.
2. Implement custom authentication middleware: Create a custom middleware to check the user's permissions before allowing access to certain routes. You can define the logic in the middleware to check if the user has the required permissions to access the route.
3. Use Gates and Policies: Laravel provides Gates and Policies to handle authorization logic. Gates allow you to define simple callbacks to authorize actions, while Policies encapsulate authorization logic for a particular model. You can define Gates and Policies to check user permissions and use them in your controllers to authorize user actions.
4. Check permissions in controllers: Use the Gates and Policies defined in the previous step to check user permissions in your controllers. You can authorize user actions by calling the authorize() method with the appropriate Gate or Policy.
5. Handle unauthorized access: If a user does not have the required permissions to access a route, you can handle unauthorized access by redirecting the user to a different page or returning a 403 Forbidden response.

By following these steps, you can effectively handle user permissions in custom authentication on Laravel and ensure that users only have access to the routes and actions that they are authorized to perform.
