Techniques for providing unified user interfaces among actively paired devices, including that first and second devices are actively paired together at a first time based on a determination that the first device is in physical proximity to the second device when the first and second devices are both authenticated for a same user service account; receiving, at the first time, an indication of an actuation of a first user interface control associated with a teleconferencing session and presented by the first device; and causing, in response the receipt of the indication and the determination that the first and second devices are actively paired together at the first time, a real-time component of the teleconferencing session to be rendered by the second device while a first user associated with the user service account is joined to the teleconferencing session as a participant.
