DotPass is a utility for generating and retrieving passwords using patterns. It lets you enter a graphical pattern and a plain-text seed word and then generates a password based on this unique combination.
As long as you enter the same pattern and seed word the generator will always output the same password. So as long as you remember the pattern you’ve chosen and your seed word, you can get your password back. Unlike other solutions, your passwords are never stored on your device or sent over the 'Net. DotPass is available for both iOS (iPhone/iPad) (available on the iTunes App Store) and OS X, so you can get access to your passwords both on your computer and anywhere with your phone/pad.
