title: How can I force login with the OAuth API?
body: <p>Is there a parameter I can pass to <a href="https://www.facebook.com/dialog/oauth" rel="noreferrer">https://www.facebook.com/dialog/oauth</a> that will force the user to login again?  </p>
  
  <p>The problem is if the user is logged into Facebook, it will redirect transparently back to my site, even if the user wants to use a different Facebook account.</p>
  
  <p>Twitter's OAuth API accepts a "force_redirect=true" parameter which does what I want, but I can't find one for Facebook.</p>
