Password manager by PasswordSafe
Popular open source single sign on application, available for free installation on a PC or on a Disk-on-Key. You can use the YubiKey in "static password" mode for use as the "Master Password". There is a new version just released (3.16.2Y here) which uses the YubiKey in "one time password" mode as well.
