title: How can I reauthenticate with Facebook after the OAuth 2.0 changes to the sdk?
body: <p>In our app we had some actions that we required the user to reauthenticate before proceeding. We used code like below to make this happen.</p>
  
  <pre><code>FB.login(
    function(response) { /* code here */ }, 
    {auth_type: 'reauthenticate', auth_nonce: '...'}
  );
  </code></pre>
  
  <p>It looks like the auth_type option is no longer supported, because I am getting the following log message: 'FB.login() called when user is already connected.' and the user is not being asked to reauthenticate.</p>
  
  <p>Does anyone have any ideas how to reauthenticate after the changes for OAuth 2.0?</p>
