An Analysis of Numerical Grid-Based Authentication

What is it about?

Passwords have been used as an authentication method for a long time. Many variations have also been proposed and applied. Grid-based passwords are also ones that have caught up with others in popularity. This research analyses the security of such system. How the way that users select cell positions in different grid sizes affect overall security of the system is investigated. How they think of the ease of use of each of the grid sizes is also studied. As a result, an attempt is then made to find a balance between security and usability.

Why is it important?

Our findings show that the locations on a grid that users tend to choose as their passwords are not evenly distributed. This leads to the fact that the security of grid-based passwords is not as high as suggested theoretically.
