Multi auth in Laravel is a feature that allows you to have multiple authentication guards in your application. This means that you can have different login systems for different types of users, such as Admin vendor and user.

Install Project

composer create-project laravel/laravel multi-auth

After installation go to user table and put below like this.

public function up(): void
    {
        Schema::create('users', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('username')->nullable();
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->string('photo')->nullable();
            $table->string('phone')->nullable();
            $table->text('address')->nullable();
            $table->enum('role',['admin','vendor','user'])->default('user');
            $table->enum('status',['active','inactive'])->default('active');
            $table->rememberToken();
            $table->timestamps();
        });
    }

Next go to .env file and put your database name

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=wz_account_admin_ms
DB_USERNAME=root
DB_PASSWORD=

Next to create seeders table

php artisan make:seeder UserTableSeeder

And put below code as well

public function run(): void
    {
        DB::table('users')->insert([
            // admin
            [
                'name'=> 'Admin',
                'username'=> 'admin',
                'email'=> 'admin@gmail.com',
                'password'=> Hash::make('111'),
                'role'=> 'admin',
                'status'=> 'active',
            ],
            // vendor
            [
                'name' => 'Ariyan Vendor',
                'username'=> 'vendor',
                'email'=> 'vendor@gmail.com',
                'password'=> Hash::make(111),
                'role'=> 'vendor',
                'status'=> 'active',
            ],
            [
                'name' => 'User',
                'username'=> 'user',
                'email'=> 'user@gmail.com',
                'password'=> Hash::make(111),
                'role'=> 'user',
                'status'=> 'active',
            ],
        ]);
    }

Next go to  DatabaseSeeder and put below code

$this->call(UserTableSeeder::class);

Next to run below command

php artisan migrate
php artisan db:seed

Next to create controller

Php artisan make:controller AdminController
Php artisan make:controller VendorController

Got to AdminController and put below code

public function AdminDashboard(){
        return view('admin.admin_dashboard');
    }

Next go to vendorController and put below code

public function VendorDashboard(){
        return view('vendor.vendor_dashboard');
    }

And check all migration would be gone in database

Next to create middleware

php artisan make:middleware Role

Go to your generated middleware and put below code

public function handle(Request $request, Closure $next, $role)
    {
        if($request->user()->role !== $role){
            return redirect('dashboard');
        }
        return $next($request);
    }

Next go to kernal.php and put below code in routemiddleware

'role' => \App\Http\Middleware\Role::class,

Next to web.php and put below code

Route::middleware(['auth', 'role:admin'])->group(function() {
    Route::get('/admin/dashboard', [AdminController::class, 'AdminDashboard'])->name('admin.dashboard');
});
Route::middleware(['auth', 'role:vendor'])->group(function() {
    Route::get('/vendor/dashboard', [VendorController::class, 'VendorDashboard'])->name('vendor.dashboard');
});

Next to go AuthenticatedSessionController and update below code

 public function store(LoginRequest $request): RedirectResponse
    {
        $request->authenticate();
        $request->session()->regenerate();
        $url = '';
        if($request->user()->role === 'admin'){
            Log::info("admin ke if me in kr gye hai");
            $url = '/admin/dashboard';
        //    return redirect()->route('admin.dashboard');
        } elseif($request->user()->role === 'vendor'){
            Log::info("vendor ke if me in kr gye hai");
            $url = 'vendor/dashboard';
        } elseif($request->user()->role === 'user'){
            Log::info("user ke if me in kr gye hai");
            $url = '/dashboard';
        }
        return redirect()->intended($url);
    }

Now php artisan serve

All setup successfully
