Single Pass

Single Pass will allow you to use a single password to compute passwords for all of your accounts, safely and securely.

What is Single Pass? Single Pass is an extension that allows you to generate passwords and PINs using a single "master" password. You only have to remember your Single Pass password and Single Pass will compute unique, secure PINs and passwords for every web site you visit. You never have to write down your passwords or 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 will be compromised! Enter your Single Pass password and a Service Name. A service name might be something like "google.com". You name the services you use in whatever way you want. You can enter "google" or "google.com" or "www.google.com" or "accounts.google.com". Note that service names are case sensitive. For better security, use cryptic service names for your services. For example, rather than use "google.com", use a password generator to create complex service names. It's OK to write down the cryptic service names in a file or put them on a sticky note, since they are useless without your Single Pass password you keep stored in your head. Using this approach also addresses the issue where some web sites require you to change your password from time-to-time or require special characters or passwords of a specific length. Once you enter your Single Pass password and Service Name, click "Compute" and Single Pass will compute a 6-digit PIN and a 16-character "Service Password" for your service. The same values will be computed every time given the same Single Pass password and service same. Note that pressing "Compute" will automatically copy the "Service Password" to your clipboard for ease of use.
