Abstract
A encrypted verification system and method includes detecting an attempt to access a service requiring multi-factor authentication from a first user computing device, requesting a trusted platform module (TPM) public key of a second user computing device, the second user computing device being coupled to the first user computing device, generating a nonce in response to receiving the TPM public key of the second user computing device, sending the nonce for signature by a TPM private key of the second user computing device, receiving a signed nonce, wherein the signed nonce is signed by the TPM private key and decrypted using the TPM public key of the second user computing device, and determining that a value of the signed nonce matches a value of the nonce to authenticate the first user computing device and allowing access to the service.
