title: Yii2 allow access to inactive users
body: <p>I need to allow access to some controllers and actions to users that are inactive.</p>
  
  <p>Those users are not guests, they have been already signed up, but not have been yet activated (they have <code>User::STATUS_INACTIVE</code> status).</p>
  
  <p>So what I need to do is to allow those users to fullfil their profiles, and only after that they should be activated from backend.</p>
  
  <p>Can't find any clues how to achieve this.</p>
