If you are a good computer user you should have a different password for each account, and should switch them frequently… which makes it pretty close to impossible to remember them. The KeePass program helps you remember them all and create better passwords, ie not your birthday. It secures them all using really strong encryption and all you have to remember is the Master Password for the program. You can keep it on a flash drive, that way you can simply plug it into a computer and go.
I am going to give a try and report back.
