Yii2: why is authentication failing?

Question

Yii

Tell me what's the problem. Authorization works, but after refreshing the page, it is no longer authorized.

if ($this->validate()) {
       return Yii::$app->user->login($this->getUser(), 3600*24*30);
} else {
       return false;
}

Returns true, but when the page is refreshed there is no authorization.

Answer 1

Check that \Yii::$app->user->enableSession = true;

Answer 2

Are there other possible problems? Maybe it's because I use password verification not using Yii, but my own encryption?
