Abstract: An administered authentication system can authenticate an artificial reality device using an authorization record between a user account and an artificial reality device. In some implementations, the authorization record is created in response to activation of a user account-specific key sent to a user-supplied contact, where an artificial reality device identifier was provided with the user-supplied contact. In other implementations, the authorization record is created in response to activation of a user account-specific key provided to the artificial reality device as a code, where activation of the key includes adding an artificial reality device identifier to a key activation message. In yet other implementations, the authorization record is created in response to an application associated with a user account activating an artificial reality device-specific key, with an artificial reality device identifier, that is provided via the artificial reality device.
