1. A method for authenticating a device with a wireless access point, including:
broadcasting, via a speaker included in the device, a requesting audio signal to request authentication information based on a determination that the device is not authenticated with the wireless access point, wherein the requesting audio signal encodes a public key of the device;
in response to the broadcasting of the requesting audio signal, receiving, at the device via a microphone, an audio signal encoding a code encrypted based on the public key of the device;
processing the audio signal to extract the code based on the public key of the device;
using the code to authenticate the device, at least in part, with the wireless access point; and
in response to the authentication, providing access to one or more network services to the device via the wireless access point.
