Techniques are described for cross-device authorization using a wireless network connection. Computing device(s) may broadcast an identification signal indicating that the device is authorized to access a remote service, and is therefore available to provide an authorization token to a receiving device. The receiving device may determine one of the broadcasting device(s) to use for cross-device authorization. The receiving device may send a request, to the determined broadcasting device, for an authorization token to access the remote service. The broadcasting device may receive the request and transmit a message to a server device indicating that an authorization token is to be provided to the receiving device. Alternatively, the authorization token may be sent directly from the broadcasting device to the receiving device (e.g., over the wireless communication network). On receiving the authorization token, the receiving device may use it to access the remote service.
