On your terminal using php artisan route:list
you will be able to see all the routes related to Laravel authentication.
Changing the views directory you should also change all the calls that were made to them. In each controller that is in the App\Http\Controllers\Auth
folder, a call is made to each of the views of the auth folder.
To change the calls, I see no other way than to override the methods that call these views.
If you do not understand, take a look at here
I forgot to mention that calls are usually made in traits that are included with Laravel itself and are stored in the vendor folder. You should never modify codes directly in the vendor folder, so I've talked about and overwritten the methods.
