Abstract
The need for secure and usable cognitive password systems has been recognized for many years. While graphical passwords present one promising approach, this study focuses on the use of short stories to create “narrative passwords”. Users are presented with a flash fiction (<1000 words) that contains interchangeable elements randomly selected for their story. These elements form the password to be remembered later, while the remainder of the story serves as a memory context to create a strong binding of the items in memory. The results of an initial pilot study using narrative passwords show that participants can retain a sufficient amount of information over a period greater than a week. The system itself acts as a memory cue, such that recognition memory performance has the potential to increase over time.
