With justOne it’s easy to use unique and strong passwords for all of your accounts. No syncing required!

You only have to come up with an account nickname and a master password. That’s the only password you’ll need to remember from now on. And it’s absolutely hassle-free, no syncing required – you’ll always have all your latest passwords with you.


How It Works

justOne uses some clever math to generate a unique password for each account. Every time you open it and enter your master password and the same account nickname, justOne will generate the same account password.
You can tap the generated password to copy it.


Secure+ vs. Oplop

justOne can generate passwords in two different ways. Oplop is a popuplar method for which apps exist on a variety of platforms. Check out http://code.google.com/p/oplop/ for details. Secure+, on the other hand, generates longer passwords from a more random selection of possible characters. That’s why it’s the default.
