Graphical passwords have been proposed as an alternative to alphanumericpasswords with their advantages in usability and security. However, they stilltend to follow predictable patterns that are easier for attackers to exploit,probably due to users' memory limitations. Various literatures show thatbaroque music has positive effects on human learning and memorizing. Toalleviate users' memory burden, we investigate the novel idea of introducingbaroque music to graphical password schemes (specifically DAS, PassPoints andStory) and conduct a laboratory study to see whether it is helpful. In a tenminutes short-term recall, we found that participants in all conditions hadhigh recall success rates that were not statistically different from eachother. After one week, the music group coped PassPoints passwords significantlybetter than the group without music. But there was no statistical differencebetween two groups in recalling DAS passwords or Story passwords. Further more,we found that the music group tended to set significantly more complicatedPassPoints passwords but less complicated DAS passwords.
