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.
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.
