How to use authentication for multiple tables in Laravel 5

Sometimes, we'd like to separate users and admins in different 2 tables.

I think it is a good practice.

So I was looking if that is possible in Laravel 5.

After a quick search, I found many people having the same question as mine.

I found some answers, but I don't think any of them is good enough.

Therefore, I spent some time digging into the source code and finally find a way to achieve this.

Answer Source

Before reading the following, you are supposed to have basic knowledge on ServiceProvider, Facade and IoC in Laravel 5. Here we go.

According to the doc of Laravel, you could find the Facade 'Auth' is refering to the Illuminate\Auth\AuthManager, which has a magic __call(). You could see the major function is not in AuthManager, but in Illuminate\Auth\Guard

Guard has a Provider. This provider has a $model property, according to which the EloquentUserProvider would create this model by "new $model". These are all we need to know. Here goes the code.

1.We need to create a AdminAuthServiceProvider.

public function register(){
    Auth::extend('adminEloquent', function($app){
        // you can use Config::get() to retrieve the model class name from config file
        $myProvider = new EloquentUserProvider($app['hash'], '\App\AdminModel') 
        return new Guard($myProvider, $app['session.store']);
    $app->singleton('auth.driver_admin', function($app){
        return Auth::driver('adminEloquent');


class AdminAuth extends Facade {
        protected static function getFacadeAccessor() { return 'auth.driver_admin'; }

3. add the alias to Kernel:

'aliases' => [
    //has to be beneath the 'Auth' alias
    'AdminAuth' => '\App\Facades\AdminAuth'

Hope this could be helpful.
