Issues in User Authentication 1
Sonia Chiasson, Robert Biddle · 2007
In this brief paper we outline our recent work on usability studies of user authentication systems. In particular, we have conducted studies on password managers and graphical password systems, using in-lab experiments, interviews, and broader field studies. We then discuss some of the important issues arising, including mental models of security, the role of persuasion, and the nature of identify theft.
