customize login in Laravel Breeze

Question

I want to customize Laravel Breeze's login logic and users can login with username and mobile for example, in previous version of Laravel, login logic uses AuthenticatesUser trait and I could override methods and customize easily, but now there is no trait and method to override. What should I do now? I search for this, and someone suggest edit the entire login logic to the previous version but I don't think its true and there is some way that I can do that without edit the whole login logic.

Answer 1

The logic now is in Http/Controllers/Auth/AuthenticatedSessionController.php in $request->authenticate(); which is located in Http/Requests/Auth/LoginRequest.php change $this->only('email', ...) to 'username' and validation also below it
