An audible authentication of a wireless device for enrollment onto a secure wireless network includes an unauthorized wireless device that audibly emits a uniquely identifying secret code (e.g., a personal identification number (PIN)). In some implementations, the audible code is heard by the user and manually entered via a network-enrollment user interface. In other implementations, a network-authorizing device automatically picks up the audible code and verifies the code. If verified, the wireless device is enrolled onto the wireless network.
