An exploration of usable authentication mechanisms for virtual reality systems

Usable security for virtual reality systems (VR) is an area that is relatively underexplored. This research investigates the feasibility of some authentication mechanisms for VR. We implemented three password methods including 3D patterns, 2D sliding patterns, and a PIN system within a VR environment. Two experiments were conducted to test the usability and security level of the three password systems. The results suggested that the 3D password system may have the highest security level among the three systems, whereas the pattern lock and PIN systems were likely to be perceived as more usable.
