I use Excel for the sites related to my own company. No one else has a copy, but there are instructions on where to find it on my desktop in the event of my incapacitation.
For a client, where several people need access, the passwords are stored with KeePass Password Safe. It's nice because the passwords aren't actually displayed- you cut and paste the password from the KeePass program to the login screen.
