Partial Login/ Register

[kenmonster]

Hello,

I'm trying to create a scenario where user can enter information without fully registering but are given the option to complete registration post success.

Thus I am creating a user via app(UserRegistration::class)->register($params)->getUserId(); but only passing an email and an auto generated password.

However, in trying to do Auth::loginUserId() I get the error

BadMethodCallException: Call to undefined method Illuminate\Database\Query\Builder::getAuthIdentifierName()

Is it that I am restricted to using the Authentication::class thus I should probably extend it?
Or am I doing something wrong here.
