How to implement multi-factor authentication in Laravel



Image not found!!

Implementing multi-factor authentication (MFA) in Laravel can be achieved using various packages and methods. One popular package for MFA in Laravel is "laravel/fortify" combined with "laravel/ui" for user interface scaffolding. Here's a step-by-step guide on how you can implement MFA in Laravel:

Step 1: Install Laravel

If you haven't already, install Laravel using Composer:

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

Step 2: Install Laravel Fortify

Install Laravel Fortify package:

bash
composer require laravel/fortify

Step 3: Set up Fortify

Publish the Fortify configuration files:

bash
php artisan vendor:publish --provider="Laravel\Fortify\FortifyServiceProvider"

Step 4: Configure Fortify

Edit config/fortify.php to configure the authentication options. Add the following to the features array to enable two-factor authentication:

php
'features' => [
    Features::twoFactorAuthentication([
        'confirmPassword' => true,
    ]),
],

Step 5: Run Migrations

Run the database migrations to create the necessary tables:

bash
php artisan migrate

Step 6: Install Laravel UI

If you haven't already, install Laravel UI package:

bash
composer require laravel/ui

Generate the basic login and registration views:

bash
php artisan ui bootstrap --auth

Step 7: Add Two-Factor Authentication Views

Edit the resources/views/auth/login.blade.php and resources/views/auth/register.blade.php files to include two-factor authentication options.

Step 8: Update User Model

Ensure that your User model implements the TwoFactorAuthenticatable contract. Open your User model and use the HasTwoFactorAuthentication trait:

php
use Laravel\Fortify\TwoFactorAuthenticatable;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use HasFactory, Notifiable, TwoFactorAuthenticatable;

    // ...
}

Step 9: Test the Implementation

Run your Laravel application and test the multi-factor authentication features.

bash
php artisan serve

Visit http://localhost:8000 in your browser, register a new user, and test the two-factor authentication process.
