In one embodiment, a system includes a processing circuit and logic integrated with the processing circuit, executable by the processing circuit, or integrated with and executable by the processing circuit. The logic is configured to cause the processing circuit to initiate a password selection session on a source augmented reality or virtual reality device (hereafter the source AR/VR device). The logic is also configured to cause the processing circuit to generate a symmetric password key according to a set of password determination rules. Also, the logic is configured to cause the processing circuit to encrypt data using the symmetric password key prior to sending the encrypted data to a receiver AR/VR device. Moreover, the logic is configured to cause the processing circuit to send the encrypted data from the source AR/VR device to the receiver AR/VR device. The symmetric password key is not exchanged with any other device.
