A method of multi-factor authentication is performed by an access control device. In response to detecting a voice command, the access control device sends a query to a location server for a current location of a user equipment (UE) included in a list of trusted UEs. The access control device may then receive an indication of the current location from the location server and in response thereto, the access control device may determine whether the current location of the UE is within a threshold distance of the access control device. If so, the access control device may generate an access signal that indicates that a user associated with the UE is authorized to access a protected resource.

Multi-factor authentication with geolocation and voice command

A method of multi-factor authentication is performed by an access control device. In response to detecting a beacon signal transmitted by a user equipment (UE) via a short-range radio access technology (RAT) the access control device sends a query to a location server for a current location of the UE. The access control device then determines whether the UE is within a threshold distance of the access control device and, if so, begins monitoring a signal strength of one or more beacon signals transmitted by the UE. If the signal strength of the one or more beacon signals exceeds a signal strength threshold, then the access control device may generate an access signal to indicate that a user associated with the UE is authorized to access a protected resource.

Multi-factor authentication with geolocation and short-range communication

A method of controlling user access to a protected area is performed by an access control device. In response to detecting a beacon signal transmitted by a user equipment (UE) via a short-range radio access technology (RAT) the access control device determines whether the UE is within the protected area or in an exterior area that is outside the protected area. In some aspects, the access control device determines whether the UE is within the protected area or in the exterior area based on the received beacon signal. In response to determining that the UE is in the exterior area, the access control device performs a multi-factor authentication procedure. If the access control device determines that the UE is within the protected area, the access control device is configured to deny access to the protected area.
