I more or less sort stuff like that into different mailboxes when it comes in. I have a separate mailbox for passwords,pins and usernames. The mail directory gets copied to the new computer when I upgrade computers. The computer from 3 years ago has been twice replaced since, but the emails are still there, at least the ones I didn't trash.
Care to come and "streamline" my desk? You know it's bad when the workspace in front of the computer is several weeks deep.
