I just wanted to chime in here…I’m having the same problem with Facebook locking my accounts and requiring password changes. Now I also can’t add any new accounts using the Session method. As soon as I enter the c_user and xs info into SNAP, Facebook immediately logs me out and ends the session.
I tried the trick with doing it from m.facebook.com. It worked with one account, but then it stopped working too.
I sent a support request a little while ago – we’ll see if anyone replies.
