YubiKey two-factor authentication (2FA) integration

A two-factor authentication system validates the user by incorporating something the user knows, normally a combination of their username and/or password, and something the user has in their physical possession, such as a YubiKey. Two-factor authentication provides high security and is often required for compliance with regulations. Two-factor authentication can also be called 2FA, two-step verification, or multi-factor authentication.
