Oct 21, 2005 For UI, I like the Emacs mode pwsafe.el. It would be nice to have some code to synchronize the PasswordSafe database with Keychain (even if it were only uni-directional) - that way we Mac users could use PasswordSafe as our primary repository but get the benefits of having OS X fill in password forms for us. Password Safe allows you to safely and easily create a secured and encrypted user name/password list. With Password Safe all you have to do is create and remember a single Master Password of your choice in order to unlock and access your entire user name/password list.
