Използвайте MongoDB с Laravel 5.3

Имам проект 5.2 и системата за удостоверяване работи добре с jenssegers/laravel-mongodb . Трябва да добавите Jenssegers\Mongodb\Auth\PasswordResetServiceProvider ако използвате напомняния за пароли.

Също така, ето моя работещ User.php , може би ще помогне:

namespace App;

use Jenssegers\Mongodb\Eloquent\Model as Eloquent;
use Illuminate\Auth\Authenticatable;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Foundation\Auth\Access\Authorizable;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;

class User extends Eloquent implements
    AuthenticatableContract,
    AuthorizableContract,
    CanResetPasswordContract
{
    use Authenticatable, Authorizable, CanResetPassword;
