An authentication system supports multi-factor authentication (MFA) when authenticating the identity of a user. A challenge-response portion of the authentication process is delegated to an MFA device-a secondary device within control of the user, but separate from the primary login device that the user is using when initiating the authentication. Communications between the MFA device and the login device are conducted using a short-range wireless communication protocol (e.g., Bluetooth™ or NFC), so that the two devices must be in close physical proximity to each other.

Transparent short-range wireless device factor in a multi-factor authentication system

A client device that is not originally compliant with a particular security standard (e.g., FIPS) is brought into compliance through the addition of a standard-compliant software-based cryptographic library. In order to adapt the cryptographic library to integrate with the hardware-backed keystore, a non-hardware-backed software keystore is used to store keys used by the cryptographic library. Additionally, in order to provide appropriate security for the software keystore, the software keystore (and/or the keypairs within the software keystore) is protected by a password, and the password is in turn protected by the hardware-backed keystore. Thus, to obtain the password needed to obtain a keypair from the software keystore that is in turn needed to use the cryptographic library, a user must authenticate with the operating system, e.g., by providing biometric credentials.
