Techniques for verifying user intent and securely configuring computing devices
The embodiments set forth a technique for enabling a computing device to securely configure a peripheral computing device. According to some embodiments, the method can include the steps of (1) approving a request received from the peripheral computing device to engage in a setup procedure for the peripheral computing device, (2) receiving, from the peripheral computing device: (i) an audio signal that encodes a password and timing information, and (ii) a light signal. Additionally, the method can involve, in response to identifying that the timing information correlates with the light signal: (3) extracting the password from the audio signal, and (4) establishing a communication link with the peripheral computing device based on the password. In turn, the method can involve (5) providing configuration information to the peripheral computing device over the communication link.

9. A method for conducting a setup procedure at a peripheral computing device, the method comprising, at the peripheral computing device:
periodically transmitting requests to nearby computing devices to engage in the setup procedure;
receiving an approval from a computing device of the nearby computing devices to engage in the setup procedure;
issuing, to the computing device:
(1) an audio signal that encodes (i) a password, and (ii) timing information, and
(2) a light signal that correlates with the timing information; and
in response to verifying that the computing device is in possession of the password:
establishing a communication link with the computing device based on the password.
