How to setup WordPress Duo Authenticator for 2-Factor Authentication?

Duo Authenticator is a mobile application that provides an extra layer of security to verify the identity of users before they can access sensitive data or systems. It is a multi-factor authentication (MFA) tool that requires users to provide a second factor of authentication in addition to their password.

With Duo Authenticator, users can receive a push notification on their mobile device, which they must approve to gain access. Alternatively, they can use a one-time passcode generated by the app to authenticate themselves.

Duo Authenticator is easy to use and provides a fast and convenient way to authenticate users. With a push notification, users can quickly approve their identity without having to type in a passcode or perform any additional steps.
