I forgot my password twice in the same day.
Luckily I didn't get the same help desk person both times.
I have about two dozen systems at work that require a password from me. I keep them encrypted on my Palm Pilot. At home, my passwords are controlled by a fingerprint reader. And I keep backups of all that on a USB drive that has its own fingerprint reader. All I have to remember is a master password, or bring along my fingers.
