As virtual reality becomes more mainstream there is a need to investigate the security of user level authentication while in the virtual world. In order for authentication methods to be useful, they must be secure, not allow for any external observers to determine the secure data being entered by the user, and also not break the immersion that the virtual world provides. Using head mounted virtual reality displays, users can interact with the world by using gaze, that is selecting objects by what the user is focusing on. This paper analyzes the security issues involved with utilizing gaze detection for secure password entry. A user study finds security issues with standard gaze based PIN input, and as a result a solution to this problem is presented. The solution shuffles the numbers on the PIN pad and finds that method to be more secure while maintaining accuracy and speed.
