PasswordMaker generates unique passwords based on address of the website and your ‘One password to rule them all’.

If you’re like most people, you have a few passwords that you use over and over again on many different websites. You know this isn’t secure, yet you do it anyway. Why? Because it’s difficult to remember a unique password for each and every web site that requires one.

PasswordMaker solves this by creating unique, secure passwords that are very easy for you to retrieve but no one else. Nothing is stored anywhere, anytime, so there’s nothing to be hacked, lost, or stolen. PasswordMaker has been around since about 2003 and so is a mature, stable, popular solution.

How it Works.

Warning - technical jargon!

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.

All computation is done on your computer. No data is sent anywhere over the internet.
