  • Guess access to a media playback system
    Patent number: 11907610
    Abstract: Example techniques may involve guest access to a media playback system. A guest may use a guest control device, such as a smartphone or tablet, to control aspects of a host's media playback system. In addition, the guest may temporarily register their user account of a streaming audio service with the host's media playback system, which enables playback of audio content from that service by one or more playback devices of the media playback system. When the guest control device de-registers from the host's media playback system, retrieval of audio content from the streaming audio service is disabled.
