title: Revoke All Refresh Tokens of User
body: <p>I'm using password grant flow, with asp.net Identity.</p>
  
  <p>I want to kill all refresh token for a user, every time a login its executed.
  I need this to kill its "session" even when he sign in with a different device, like other pc, or smartphone.</p>
  
  <p>So, how can I do it?</p>
  
  <p>Can I just do a <code>UserManager.UpdateSecurityStampAsync(user.Id);</code>, or I need something else?</p>
  
  <p>Thank you so much for your help!</p>
