Registration and Login with Username or Email

To start with this, we have to add a custom login and registration page to our Panel Provider:

app/Providers/Filament/AdminPanelProvider.php:

use App\Filament\Pages\Login;
use App\Filament\Pages\Register;
 
// ...
 
class AdminPanelProvider extends PanelProvider
{
    public function panel(Panel $panel): Panel
    {
        return $panel
            ->default()
            ->id('admin')
            ->path('admin')
            ->login(Login::class) 
            ->registration(Register::class) 
            ->colors([
                'primary' => Color::Amber,
            ])
            // ...

Next, we need to create these two pages:

php artisan make:filament-page Login
php artisan make:filament-page Register

This will create two files that we can modify and add our custom fields:
