I use a tool for this so that I don't have to remember anymore.
KeyWallet
http://www.keywallet.com/
It stores passwords and other information encrpyted on your computer or exportable to take with you to a floppy or other media.
Password protected so it is secure.
Now the reason I am posting about this:
I have had 5 instances this year with having to find info on comps for dearly departed...
Don't let your loved ones go through this problem as it is nearly impossible to find everything you need from a computer once that person is gone. Much of thier life will be locked away and you won't have access to it.
Do your loved ones a lovely thing and store them in some kind of fashion for them to retrive if something happens to you.
