I have way too many passwords to remember. I need passwords for the Windows network login, Linux network login, three different e-mail account, ftp password, online passwords, work accounts, home accounts, etc. etc. etc. The list is endless. Also, I need to use different passwords for each account because I can't trust that every person at every location will be honest.

KeePass is a free/open-source secure password manager or safe which helps to manage passwords in a secure way. KeePass stores passwords, usernames, urls, notes into a single database encrypted using AES and Twofish.

The best part is the database can be read by both the windows and Linux clients. I have not played with it yet, but there is also a thumb drive version which can be run totally self contained on a portable USB drive.
