Executive Summary

People have difficulty remembering multiple passwords. This results in reduced security as users reuse the same password for different systems or reveal other passwords as they try to log in. It can also lead to reduced privacy, as users may rely on centralized services to manage their passwords. In this paper, the authors report on a laboratory study comparing recall of multiple ordinary text passwords with recall of multiple click-based graphical passwords. They found that participants in the graphical password condition coped significantly better than those in the text password condition.
