Augmented Reality (AR) Head-Mounted Displays (HMD) are increasingly used in industry to digitize processes and enhance user experience by enabling real-time interaction with both physical and virtual objects. In this context, HMD provide access to sensitive data and applications which demand authenticating users before granting access. Furthermore, these devices are often used in shared spaces. Thus, shoulder-surfing attacks need to be addressed. As users can remember pictures more easily than text, we applied the recognition-based graphical password scheme “Things” from previous work on an AR HMD while placing the pictures for each authentication attempt in a random order. We implemented this scheme for the HMD Microsoft HoloLens and conducted a user study evaluating Things's usability. All participants could be successfully authenticated and the System Usability Scale (SUS) score is with 74 categorized as above average. We discuss as future work how to improve the SUS scores, e.g., by using different grid designs and input methods.
