1. A method for authentication of user devices, the method comprising:
performing an authentication of a first user device to a media device, wherein:
an authentication token that indicates an identity of the media device is associated with the authentication of the first user device to the media device, and
an identifier of the first user device is included in an access control list maintained by a server system, wherein the access control list indicates devices that are authenticated and provided with media playback control on the media device;
identifying, using the first user device, a second user device in proximity to the first user device;
transmitting, using the first user device to the second user device, an invitation message to authenticate the second user device to the media device, wherein:
interaction with the invitation message causes the authentication token to be transferred from the first user device to the second user device,
the authentication token is transmitted by the second user device to the server system to authenticate the second user device to the media device,
the second user device is added to the access control list maintained by the server system, and
after the second user device has been authenticated by being added to the access control list, a media content item selected using the second user device is transmitted to the media device for playback; and
removing, by the server system, the second user device from the access control list maintained by the server system based on proximity of the second user device to the media device, wherein
removing the second user device from the access control list prevents the second user device from selecting media content items for playback by the media device.
