auth extension advice

Hi All,

after some years of development with Yii1 i’m starting a new application with Yii2.

so now I need an advice to a good replacement of auth extension that i used in my last Yii1 application:

http://www.yiiframework.com/extension/auth/

there is an equivalent extension for Yii2 or i have to develop my authentication system by my self?

thx to all
