Bank account information.

So, apparently all I need is your mother's maiden name and your bank will pretty much let me have access to your account. Mother's maiden name = Golden Ticket. Huh... So... In the encryption world, your mother's maiden name is more indecipherable than say... the enigma machine? The person on the phone always asks you for it like it is 1963 and you are at an East German checkpoint trying to get back into West Berlin. "So! Vat is zee mudder's maiden name???" I'm always ready for the follow up question which I'm sure will be "Who is the pitcher for the Brooklyn Dodgers?" I guess the sanctity of motherhood is so sacred that no one dare steal such precious information.

since so many women now do not change their names on getting married.
