There's an article here about a survey where people were asked about login information like passwords. The conclusions are kind of interesting but definitely not new to me or anyone with some sysadmin experience and/or tech support experience.
In the subtitle of the article you can read "More than 70% of people would reveal their computer password in exchange for a bar of chocolate, a survey has found.". I would give away my computer password to. For starters, I really like chocolate. I could then go home and change my password while eating my free chocolate. :)
