Abstract: Migration of a pairing of wearable device to a new companion electronic device is disclosed. In one embodiment, pairing migration is performed by syncing and verifying a migration key in the wearable and new companion device. Pairing migration includes moving settings and pairing data of the wearable to the new companion device in response to detecting the wearable is associated with the migration key, wherein the migration key establishes a validation of trust of the wearable relative to the companion device. The settings and pairing data can include configuration and protected data and one or more keys to establish a trust relationship between the wearable and new companion device. The settings and pairing data can also include device data such that the wearable can be discoverable by the new companion device.

Abstract: Systems, methods and non-transitory computer readable media for allowing a user to switch between wearable items that have been paired or associated with an electronic device, such as a smartphone, are described. In one embodiment, the wearable items automatically detect a removal of a first wearable item from a user's body and an attachment of a second wearable item to the user's body. Messages from the wearable items are transmitted to the electronic device to allow the electronic device to switch the active wearable item from the first wearable item to the second wearable item. The switch can occur while the electronic device is in a locked state, and the electronic device can synchronize the second wearable item with data received from the first wearable item. Other embodiments are also described.

Abstract: In some implementations, a computing device can transfer a playback queue between the computing device and a playback device. For example, the computing device can detect when the computing device is within a threshold distance of a playback device. The computing device can establish a connection to the playback device and receive state information describing the media playback state of the playback device. The computing device can determine the media playback state of the computing device. The computing device can present graphical user interfaces for initiating a transfer of a playback queue between the computing device and the playback device based on the playback state of the devices. The computing device can initiate a transfer of the playback queue in response to user input to one of the graphical user interfaces or automatically based on the context of the computing device.

Abstract: In some implementations, a computing system can be configured so that a first user device can delegate a first user's media account credentials to second user device corresponding to a second user. For example, a playback device may be configured with the second user's media account credentials for accessing media items through a network media service. A first user may wish to play media items associated with the first user's media account credentials on the playback device. To do so, the first user device can request a device identifier for the playback device, request and obtain a delegate token for the device identifier from the media service, and provide the delegate token along with media item information to the playback device. The playback device can then use the delegate token to request the media item associated with the first user's media access account.
