Single Pass

What is Single Pass?

Single Pass™ is an application and web site that allows you to create passwords using a single "master" password. You only have to remember your Single Pass password and Single Pass will generate unique, secure passwords for every other web site you visit. You never have to write down your passwords and risk somebody stealing your passwords with Single Pass.

How do I Use Single Pass?

First, select a complex Single Pass password that only you know. Don't write it down where it can be stolen. Memorize it. This will be your key to everything! If somebody steals your Single Pass password, all of your generated passwords could be compromised!

Enter your Single Pass password and a "Service Name". A Service Name might be something like "". You name the services you use in whatever way you want. You can enter "apple" or "" or "". (Note that "Apple" and "apple" are different Service Names, as Single Pass is case-sensitive.)

Even better, consider using a password generator to create really complex Service Names and write those down in a secure location. A hacker would need to know both the exact Single Pass password and Service Name in order to generate your password. Complex Single Pass passwords and Service Names stored in separate places (your head and a file on your computer, respectively) can help to protect your valuable information. In this way, you have a strong, unique password for every web site that is not stored in a single place where a hacker may gain access.

Once you enter your Single Pass password and Service Name, click "Compute" and your web browser will compute a 16-character Service Password for the web site you are trying to access. Single Pass will consistently generate the same values for the given Single Pass password and Service Name.

In order to protect your privacy, data entered on this page is processed locally in your browser and never transmitted to our servers.

That's it! You are no longer forced to memorizing dozens of passwords or write down hundreds of passwords. You only need to memorize one!
