Graphical Passwords
This is an interesting new take on user authentication, and works something like this:
- You create a graphical password by choosing a small subset of the pass-icons in the system.
- The authentication screen shows a random grid of icons, with at least 3 of them being ones that are part of your password.
- You need to find at least 3 of your chosen icons, and click inside the imaginary area (the convex hull) that is formed with your icons as the vertices.
- The icons are shuffled and you repeat the process a preset number of times to minimize the chances of lucky guesses. If you have enough correct clicks you are authenticated.
Quite a novel concept. It could be useful in some places, but will probably be too cumbersome to use for all of your passwords.
