Abstract: A method of adding a user account to an unassociated device may include detecting, by an associated device that is associated with a user account, an audio signal broadcast by an unassociated device that is not associated with the user account, where the audio signal includes a token. The method may include sending the token to a computing device associated with a service provider of the user account, receiving, by the associated device, a command, determining that the received command is an authorization command, and in response to determining that the received command is an authorization command, sending one or more authorization instructions to the computing device. The one or more authorization instructions may instruct the computing device to send one or more credentials associated with the user.

Abstract: The subject technology provides for detecting, by a first computing device, a second computing device being within a predetermined distance of the first computing device, the first computing device being in a locked mode. The subject technology receives an access key from the second computing device. Additionally, the subject technology exits, by the first computing device, the locked mode based on the access key from the second computing device.
