Use MongoDB com Laravel 5.3

Eu tenho o projeto 5.2 e o sistema de autenticação funciona bem com jenssegers/laravel-mongodb . Você deve adicionar Jenssegers\Mongodb\Auth\PasswordResetServiceProvider se você estiver usando lembretes de senha.

Além disso, aqui está meu User.php de trabalho , talvez ajude:

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;
