Password Keeper is a freeware program to keep all of your passwords safe with a single, master password using Simple 3DES encryption.
Password Keeper was sent to us by a lone developer who created the app and wanted to share it. There's currently no website, but there is an included help.
That said, it's a very simple app to use. You can add, edit or delete from the buttons on the main window. From the "File" tab you can open, save, backup or restore. Backup allows you to save your entire list of passwords somewhere else in a proprietary file.
You can also view your saved passwords by details, list or tile. Options allow you to set your master password and show encrypted data. You need to setup a password. Otherwise, all your passwords are readily viewable. While this might not make sense to some, some people are glad just to save their passwords and not worried about someone accessing them.
There's a lot of competition in password managers, but if you're looking for simplicity and ease of use, Password Keeper might be just what you're looking for.
