Learning a Strong Authentication Secret by Leveraging the Method of Loci and a Computer Game
MetadataShow full item record
System-assigned random passwords offer a lot of security benefits over traditional user-chosen passwords but suffer from memorability issues. In this work, we focus on resolving this memorability issue by designing two training methods that would help users in memorizing a system-assigned random password of twelve lowercase letters. We first leverage the method of loci to dynamically generate a training video clip, which leverages the spatial and visual memory of a user. We also design a computer game to consolidate the learning process. We conducted a user study to test the effectiveness of our training methods. Our study results show that compared to previous studies, participants in our study were able to better recall the long random password and login more quickly. The participants also expressed a high level of satisfaction with our training interface. This suggests that our training interface could be leveraged to help users memorize a strong random authentication secret in just one training session.
