The Problem

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.

The purpose of PasswordMaker is to enable you to securely and easily log in to Internet applications, such as websites, instant messaging, ftp, and others. With the proliferation of online resources, you probably have usernames and passwords for banks, bill pay systems, email accounts, credit card websites, instant messenger, investment accounts, photo sites, blogging tools, and countless others. Most people have a few passwords they use for all of these accounts because it's easier to remember just a few. But this is incredibly risky.

What if you could use passwords unique as fingerprints for each and every one of your accounts, yet not have to remember those fingerprints? PasswordMaker does just that. By using complex mathematical formulae, PasswordMaker outputs the same unique passwords for you each and every time you provide it with the same input. And these passwords are unique across the globe (providing they are of sufficient length).

But only a genius could memorize so many unique passwords. Don't write them down on sticky notes for others to find; no, PasswordMaker calculates them for you over and over again -- as needed -- without storing them so they can't be stolen. And if you use more than one computer (for example, one at work and one at home), it's child's play to synchronize them. There's even an on-line version for times when you are at a public computer and can't install any software.

Existing Solutions

Maybe you do use unique passwords, and get around the problem of remembering them by storing them in a spreadsheet or other file. Maybe you even use one of the many password managers that are available. But now you've centralized your passwords and access to them becomes difficult while at work, a friend's, or a public internet terminal. You can't get to your passwords without carrying them around or publishing them on the internet. Some people even carry a USB keychain with their passwords wherever they go. How inconvenient. And publishing them on the internet? Yikes! We need not even mention the security risks inherent with that solution. Even if you trust the company storing the passwords, you can be sure every hacker in the world is drooling over the prospect of accessing their database.

The Solution

PASSWORDMAKER solves all of these issues. It is a small, lightweight, free, extension for 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 there's nothing to be hacked, lost, or stolen.

How It Works

You provide PasswordMaker two pieces of information: a master password -- that one, favorite password you like -- and the URL of the website requiring a password (for internet applications without URLs, such as instant messaging, you can make up any URL you like; e.g., aolinstantmessenger.com). Through the magic of one-way hash algorithms, PasswordMaker calculates what is known as a digital fingerprint - or hash - which can then be used as your password for the website. Although one-way hash algorithms have a number of interesting characteristics, the one capitalized on by PasswordMaker is that the resulting hash (password) does "not reveal anything about the input (your master password) that was used to generate it." [1] 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 won't help! Other security features, such as PasswordMaker's ability to automatically insert generated passwords into web sites' password boxes, helps protect you from key-loggers and/or trojan horses that some Black Hats use to try to steal passwords.

What About Portability?

For times when you must use non-Firefox browsers or can't install Firefox extensions, there's an online version which mimicks the extension and works in all browsers new and old. No downloads or installations are required. Additionally, stand-alone versions for desktops, mobile phones, and PDAs are coming shortly.
