This login throttling only works for your regular authentication. Nova uses its own authentication controller and therefore. For that controller, the throttling is not enabled.
You can override this behavior by overriding the LoginController from Nova if you wish.
// app/Providers/NovaServiceProvider.php
namespace App\Providers;
class NovaServiceProvider extends NovaApplicationServiceProvider
{
public function register(): void
{
$this->app->bind(
\Laravel\Nova\Http\Controllers\LoginController::class,
\App\Controllers\Nova\LoginController::class
);
}
}
You can then either copy over the Nova controller or extend that class. You're free to do whatever you want with the controller at this point.
