For simple duplication, you could record each login and password, then store that document in a safe or somewhere only you have access. An off-side duplicate, such as a bank deposit box can be an aditional backup. Encrypted password-storage applications, such as SplashID andeWallet work even better, because even if someone else gets access to your password file, they won't have a way to unlock it.Finally, you can create a Windows Vista password reset disck that will store a special unlocking key, in case your memory--and access--are blocked later. Insert a thumb drive, and visit the User Accounts Control Panel. Pick Create a password reset disk as a Task, and follow the wizard's instructions to enter your current password. Lock the thumb drive in a safe. If you ever need to use it, click Reset Password at the Vista login screen to restore access.
