PasswordMaker project is a small, lightweight, free, extension for Internet Explorer, Firefox, Mozilla, Netscape, Flock, and Yahoo! Widgets which creates unique, secure passwords that are very easy for you to retrieve but no one else. Nothing is stored anywhere, anytime, so theres nothing to be hacked, lost, or stolen.

How It Works:
You provide PasswordMaker two pieces of information: a "master password" -- that one, single password you like -- and the URL of the website requiring a password. Through the magic of one-way hash algorithms, PasswordMaker calculates a message digest, also known as a digital fingerprint, which can be used as your password for the website.

Although one-way hash algorithms have a number of interesting characteristics, the one capitalized by PasswordMaker is that the resulting fingerprint (password) does "not reveal anything about the input that was used to generate it." In other words, if someone has one or more of your generated passwords, it is computationally infeasible for him to derive your master password or to calculate your other passwords. Computationally infeasible means even computers like this wont help!
