1. A computer-implemented method, the method comprising:
sending, by a user device, a service request to a server computing system;
establishing, by the user device, a service session with the server computing system;
outputting, by the user device, a first audio signal generated based on a challenge audio file received from the server computing system;
receiving, from a playback device, a second audio signal generated by the playback device based on the first audio signal, the second audio signal encoding a code that corresponds to a user of the user device; and
sending, by the user device, a playback of the second audio signal that encodes the code to the server computing system, thereby enabling the server computing system to verify an identity of the user by extracting the code from the second audio signal.
