The Handbook of Different Authentications for Security
Two Factor Authentication
Make your account much more secure with two factor authentication. You will need a client app that supports the protocol before being able to use this service. You can find common client applications below.
Client Applications:
One Time Use 2FA Codes
Your one time use 2FA codes can be used as a second factor if for some reason you do not have access to your normal 2FA application or security key. These should be stored securely in a safe location.
Web Authentication (WebAuthn)
WebAuthn is a new W3C global standard for secure authentication on the Web supported by all leading browsers and platforms. We can make WebAuthn as a second factor login option.
You can read more about WebAuthn at yubico.com/webauthn.
