Virtual reality (VR) is a growing technology with social, gaming and commercial applications. Due to the sensitive data involved, these systems require secure authentication. Shoulder-surfing, in particular, poses a significant threat as (1) interaction is mostly performed by means of visible gestures and (2) wearing the glasses prevents noticing bystanders. In this paper, we analyze research proposing shoulder-surfing resistant schemes for VR and present new shoulder-surfing resistant authentication schemes. Furthermore, we conducted a user study and found authenticating with our proposed schemes is efficient with times as low as 5.1 seconds. This is faster than previous shoulder-surfing resistant VR schemes, while offering similar user satisfaction.
