Hi @christaiwo ,

The easiest way for you to do this will be to create your own logic for creating users and pass it into the authenticate method. see example below. and that will throw an error while attempting to create new users.

 // in auth.php
Route::get('authenticate', function (AuthKitAuthenticationRequest $request) {
    return tap(redirect()->intended(route('dashboard')), fn() => $request->authenticate(createUsing: function ($workosUser) {
        throw new Exception('No one is allowed to login yet.');
    }));
})->middleware(['guest']);
