Abstract: The systems and methods provided herein use a rolling voice identifier in a multi-factor authentication system to avoid the security problems present in prior voice activated control systems. By implementing a rolling voice identifier in an access control platform, users may no longer need to be concerned with being overheard or recorded when providing voice authentication commands to an access control platform because the rolling voice identifier that the user will be prompted to speak will be specific to the particular instance of control of an access control platform. An access control platform is a platform that controls operation of a movable barrier by, for example, controlling the state of a movable barrier using a remote control. An access control platform may cause a movable barrier to become opened, closed, locked, or unlocked to permit or prevent access to a physical space by a physical object.
