I accidently typed in my facebook password when logging into gamefaqs (my gamefaqs password is different from my facebook one)

Now I'm guessing Gamefaqs has my password and the admins and mods can see it. Granted they don't know my email for facebook (also different from the one i used to sign up here)...but they already have half was what they need. I don't want to change my facebook password because the last time I did that i got locked out of my account.

What should I do?
