In one embodiment, a method includes receiving an eye gaze of a source user generated by a source augmented reality or virtual reality device (source AR/VR device) on a receiver AR/VR device. The method also includes determining gazed content from the eye gaze of the source user using a password key phrase determination feature. In addition, the method includes generating a symmetric password key utilizing the gazed content according to a set of password determination rules. Moreover, the method includes performing an operation using the receiver AR/VR device, the operation being secured by the symmetric password key. The symmetric password key is not exchanged with any other device. Other systems, methods, and computer program products for generating a symmetric password key from an eye gaze are presented in accordance with more embodiments.
