This is awesome! thanks for the help, I'm trying to do the same in Laravel 5.4 but I get an error in AuthServiceProvider.php Argument 1 passed to App\Authentication\UserProvider::__construct() must be an instance of Illuminate\Contracts\Hashing\Hasher, none given, called in app\Providers\AuthServiceProvider.php on line 32 and defined', 'app\Authentication\UserProvider.php I think it has something to do with the new registerPolicies but I don't know how to implement this. Could you help me with an example of how to create the AuthServiceProvider boot function in Laravel 5.4? thanks!

Hello,
I'm using this architecture for my project,
I have a simple question, how do you access the UserProvider instance ?
I'm trying to get a user by ID...
Thanks

Mine say that "Class 'App\Providers\UserProvider' not found.
I'm using Laravel 5.5

UserProvider.php is missing the include: use Illuminate\Contracts\Auth\Authenticatable;

I'm using 5.5 and I have :
Declaration of App\Authentication\UserProvider::updateRememberToken(App\Authentication\Authenticatable $user, $token) must be compatible with Illuminate\Contracts\Auth\UserProvider::updateRememberToken(Illuminate\Contracts\Auth\Authenticatable $user, $token)

Could you please update this to 5.6?

Declaration of App\Authentication\UserProvider::updateRememberToken(App\Authentication\Authenticatable $user, $token) must be compatible with Illuminate\Contracts\Auth\UserProvider::updateRememberToken(Illuminate\Contracts\Auth\Authenticatable $user, $token)

I fixed it by adding this line:

use Illuminate\Contracts\Auth\Authenticatable;
