title: FB.logout() - no access token - "Log in as Different User"
body: <p>This question is in relation to this question:  <a href="https://stackoverflow.com/questions/8430474/fb-logout-called-without-an-access-token/10739999">FB.logout() called without an access token</a></p>
  
  <p>I had a question i was hoping someone could help with.</p>
  
  <p>I get everything in the link above, but how do you handle when someone uses a public computer and leaves themselves logged in to FB by accident? Then a new user tries to log in to an app, but it is not them. I want to have a button to log them out of FB altogether to "log in as a different user".</p>
  
  <p>I cannot do that until they authorize the app, right? So they need to authorize the app under someone else's account and then log out? There has to be another way.</p>
  
  <p>Any feedback would be great - tried searching for a while on this, but to no avail. I might be over thinking it, but there should be some way to "log in as a different user".</p>
