This just happened two days ago and it has worked fine and I never changed my settings or anything what is going on?

I'm in the same boat. Stopped working for me about a month ago, keeps asking me to reenter my password. I've been using this app http://fbmacmessenger.rsms.me ever since which works great but it is not an official facebook app.
