The whole "secret question" thing seemed to me to a completely stupid idea from the start. "Hey, give us password. If you forget your password, give us a much, much less secure way to access your account." I've always given false info to those, when I bother to fill them out at all. If necessary, I just store this false info along with the password in the encrypted file I keep my passwords in. The security questions…
That said, I have a peeve with one of the standard questions they ask, which is the "favorite" question. Favorite movie, favorite band, favorite song, etc. Besides the fact that I don't have One Favorite anything, does anyone actually have life-long singular favorite things? How the hell should I know what my favorite movie was 3 years ago when I rushed through some account creation process on some random website?
