Change Password UI Study

Conventional wisdom seems to have concluded that traditional passwords are inherently insecure. The argument is usually that users choose bad passwords and cannot be expected to remember strong passwords. We feel that these conclusions are premature and that this argument is flawed. At present most password selection mechanisms are not designed according to basic HCI principles and we believe that this is highly responsible for the above conclusions. Our current research is reexamining the problem of password selection and memorability through the exploration of password selection mechanisms with novel interface designs. The goal of this research is develop both principles and designs that help users to choose passwords that are both memorable and secure.

To conduct the original study I implemented a homework submission system in PHP. It is is online at Students used the system like a normal system, with the Java applets above integrated for password selection. At the end of the semester I got consent from stuents to view their Password Quality Score data and tabulate results.
