how to set new guard for auth controller in larave

Question

I want to make multiple authentication in my laravel project.

I create new guard "admin" in my auth.php file but I don't know how to set new created guard in my authcontroller.

It always use "defaults" settings from my auth.php:

'defaults' => [
    'guard' => 'web',
    'passwords' => 'users',
],

Answer 1

1) If you wish to use newly created admin guard throughout the application, you can change the value in defaults of config file.

2) If it is only about AuthController that uses Laravel's in built Auth system, you can add this line in the AuthController.php and PasswordController.php :

protected $guard = 'admin';

3) If you wish to you a guard other than default one for any Auth related task, you can specify it manually like this :

// For route middleware
Route::get('profile', [
    'middleware' => 'auth:admin',
    'uses' => 'ProfileController@show'
]);

// For manually logging the user in
if (Auth::guard('admin')->attempt($credentials)) {
    // Authenticated...
}

// To login specific user using eloquent model
Auth::guard('admin')->login($user);

// For getting logged in user
Auth::guard('admin')->user();

// To check if user is logged in
if (Auth::guard('admin')->check()) {
    // Logged in
}

Answer 2

Laravel 5.4+ uses the following in any Auth Controller:

use Illuminate\Support\Facades\Auth;

protected function guard(){
   return Auth::guard('guard-name');
}

Answer 3

You have to also register the guard in the config\auth.php

'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],

    'api' => [
        'driver' => 'token',
        'provider' => 'users',
    ],

     'admin' => [
        'driver' => 'session',
        'provider' => 'admins',
    ],
],

admin is the guard name, provider is the TABLE-NAME
