I took the painful steps to alter the [php artisan make:auth] authentication/registration scaffolding by altering the User model. In a nutshell, I renamed the User model to AccountLogin because I already have a Users table (which holds an email address). I also modified the model to authenticated using a username vs. email.

The registration/login work great. However, when I attempt to reset my password I receive an error that my AccountLogin model doesn't have an email column (which is accurate because it's in another table). I tried altering the AccountLogin model using a public function getEmailAttribute() but the scaffolding doesn't call the Model->email attribute.
