What can replace CWebUser and CUserIdentity in Yii 2.0?

Question

Yii

I'm rewriting authorization to Yii 2.0, where I use calls like Yii::app()->user->getState('department'), ->getId, etc.
CWebUser, as far as I understand, was completely removed from Yii 2.0. What came to replace him?

Answer 1

'user' => [
            'class' => \yii\web\User::className(),
            'identityClass' => common\modules\user\models\User::className(),
        ],
