Most Web sites that contain secure personal information require a password also have at least one password hint in case you forget. It typically goes like this: You sign up for something like online banking and you get a login and password and then choose a security question for when you forget your password. What's the name of your first pet? What's your mother's maiden name? What was your high school mascot? What's the name of the first street you lived on? Including any of these details on a Facebook wall or status update may not seem like a big deal, but it could provide an identity thief with the last piece of the puzzle needed to hack into your bank account. Think before you post anything that could compromise this information.
