title: Invalidating a facebook access token?
body: <p>Is it possible to invalidate a facebook access token? </p>
  
  <p>I need to do this due to the recent deprecation of offline_access. </p>
  
  <p>The problem is that the token cannot be extended beyond 60 days. Even if the user returns to the app (unless I am misunderstanding?)</p>
  
  <p>So, what I want to do is invalidate the token, then immediately log the user back in so that I can get a new access token back, with a new 60 day expiry date. As long as the user comes by once every two months, everything should be OK.</p>
  
  <p>I do not want to log the user out of Facebook so FB.logout is not usable.</p>
  
  <p>Is that possible?</p>
