How to restrict guest access to the admin panel?

Question

Yii

Good evening. Can you please tell me how in Yii it is possible to restrict a guest's access to the admin panel and, when entering any page of the admin panel, give him a login view? What is the best way to do this? Inherit one controller to another? Use the init() method? Tried to make a simple redirect:

if (Yii::$app->user->isGuest) {
            return $this->redirect('/admin/login');
        }

But a cyclic redirect occurs, the page forwards to itself.
