How to Change the Guest Redirection URL in Laravel 12

To change the path that guests are redirected to when attempting to access an unauthenticated area, head to bootstrap/app.php.

You'll need to call the redirectGuestsTo method within the withMiddleware callback.

return Application::configure(basePath: dirname(__DIR__))
    //...
    ->withMiddleware(function (Middleware $middleware) {
        $middleware->redirectGuestsTo('/auth/login');
    })
    ->withExceptions(function (Exceptions $exceptions) {
        //
    })->create();

Once you've done that, guests that are attempting to access an area of your application protected by auth middleware will be redirected here.

And as a side note, while it would be convenient to be able to use the route helper here to reference a named route, unfortunately this doesn't work, since helpers and Facades are not loaded at this stage of Laravel's lifecycle.
