I think I really screwed up?

To make a long story short, I was in 1 room and my wife called me in to see why her keyboard wasn't working.So I go in not knowing what she was doing and just strummed the keyboard and found out I just set her new password on yahoo.We have no clue what I typed and can't get in to reset it.Needless to say I didn't make her day.And her send to in case address was a real old netscape address that is closed.Anyone have any help?
