System and method of multi-party computation based multi-factor authentication

Abstract

Systems and methods of performing multi factor authentication (MFA), including: receiving, by a computing device, an MFA request from a first server, generating, by the computing device, a first share of a cryptographic key, based on a multi-party computation (MPC) protocol, generating, by a second server, a corresponding second share of the cryptographic key, based on the MPC protocol, wherein the cryptographic key corresponds to a public key and private key pair, co-signing, by the computing device and the second server, the MFA request based on the MPC protocol, wherein the computing device signs the MFA request with the first share and the second server signs the MFA request with the second share, and verifying, by the first server, the signed MFA request.
