2FA (two-factor authentication): An additional layer of authentication beyond a username and password. 2FA involves something you know (password) plus something you have with you (like a code from Microsoft Authenticator App or a code generated from your iphone) to prevent someone from logging in with only your password if your password was leaked or hacked or someone you knowingly or unknowingly shared your password with. With 2FA, you still enter your username and password. The second factor provided by Duo is simply an added layer of security on top of your existing credentials.
We recommend using your iPhone to setup 2FA - Simply scan the QR code generated during 2FA setup using your iPhone camera. Tap on the link on the camera window, and complete setup using either selecting the login credentials already saved in iPhone passwords and associating with it or saving it. You need to enter the generated code into the 2FA setup screen. Also, don't forget to save the backup code as you will need it to reset 2FA. You may also use Microsoft Authenticator or Google authenticator to setup 2FA.
