Technologies for securely pairing a first computing device with a second computing device include the first computing device to generate a session message key based on a key exchange with the second computing device. The first computing device receives a message including a hardware key certificate, 5 a cryptographically-signed communication, and a message authentication code from the second computing device. The cryptographically-signed communication is signed with a private hardware key of the second computing device. The first computing device validates the message authentication code, the certificate, and the signature received from the second computing device. After validation, the first computing device 10 identifies a user of the second computing device based on user-identifying data received from the second computing device.
