Magic Password Generator Downloads

Magic Password Generator is a Firefox addon designed to generate passwords based on a single master password. Also fills in username and email address fields.

The idea is that it is more secure to give every website a different password. If one site has naughty administrators, or gets hacked, the same compromised password won't work for your account on another site. But how can one remember a different password for every site? Don't, let the computer make one for you!

You remember one master password. (It is not stored anywhere, don't forget it!) Then, with a (somewhat simple) cryptographic hash function, the extension combines your master password and the domain name of the site to make another unique password for that site. The password is not saved in Firefox, or anywhere else. It's secure!
