The experts tell you to use a different password for every system and to change them often.
So how do you keep track of them all?
SafeInHand is a simple password protector. It uses a light, custom encryption routine to prevent casual eyes from prying. It automatically backs up the file every time you use HotSync.
SafeInHand also generates random passwords for you. There is a button labeled "Dupe" that allows you to make duplicates of entries. The view screen also has a checkbox at the top labeled "Keep Alive" that keeps that screen from being automatically closed when the power is shut off.
