Facebook stymie

Facebook has new security thingy where you have to identify 5 friends' pictures. I have over 100 "friends" as neighbors in games and don't recognize most of them. I got 4 pictures right (they offered me ones of family and actual friends) but the 5th was a mystery. Since I can't log in I am stymied.

This is really annoying. Suppose I was blind? Now I can't play Words With Friends or MonsterBusters and that is hard on a game addict. Can anyone think of anything to do to get Facebook to see reason?

I assume others are confronting this and not just me.
