Abstract
Techniques are provided for basic input/output system (BIOS) protection using multi-factor authentication (MFA) based on digital identity values. One method comprises obtaining, by a BIOS of a hardware device, from a user device, (i) a request to access the BIOS, and (ii) a token based on a digital identity value for the user device; providing the token to an MFA chip on the hardware device, wherein the MFA chip evaluates the token and provides a verification result to the BIOS; and allowing the user device to access the BIOS based on the verification result. The digital identity value for the user device may be stored by the MFA chip during a fabrication of the MFA chip and/or a registration of the user device. The MFA chip may compare the digital identity value from the token received from the BIOS with the digital identity value for the user device stored by the MFA chip.
