With the Facebook Graph API, is there a way to get a new access token without needing to re-enter the user's password?

My app uses Facebook Connect. When the access token expires, I take the user to the URL described in [1]. Then Facebook shows a page where the user has to enter his password, even though the user has authorized my app before. Is there a way to refresh the access token without a password? [1] http://developers.facebook.com/docs/authentication/
Answer:

While the OAuth 2.0 spec has a "refresh" token call, FB has chosen a different method. You can exchange your token for a long life token (http://developers.facebook.com/docs/howtos/login/extending-tokens/) Once this token expires, you'll have to pass the user through the login flow.

Facebook has removed the feature of refresh the access token on the "behalf of" mode. The best and easy way is to redirect the user to facebook login page to re-oauth the app. Find facbook doc here: https://developers.facebook.com/docs/facebook-login/access-tokens#extending

Long lived access tokens work differently for a user vs a page. Even with a long lived user access token you will still be required to reauthorize in the future.
