How do I enroll in phone (voice) notifcation (2FA)?

How to enroll in phone (voice) notifications for 2FA:

1. If you previously enrolled in Butler two-factor authentication, reset your 2fa by going to 2fa.butler.edu. 
2. On a computer: go to my.butler.edu or office.com (note: alumni should go to office.com, as they do not have access to my.butler.edu). On the login screen with the bulldog, enter your full Butler email address and password, then click Log In. (If you have signed in previously, you will need to clear your browser history or use a new private (incognito) window).
3. Choose the "Phone Call" option. Please note: you can only choose one option.
4. On the "Secure your account" screen, enter your 10-digit phone number
5. Choose Call
6. You will get a phone call with a 6-digit code
7. Enter the code
8. Click Continue.
9. On your computer screen, you will see a 24-digit alphanumeric recovery code. Treat this recovery code as you would a password. It is important that you record this recovery code and keep it in a safe place. Suggested: take a photo of the code, and then transfer the code to a safe place that you can access without your mobile device (examples: cloud storage folder, password management app, personal non-Butler email account). In the event that you lose your device or get a new device, or in the event you don't have your device with you, this recovery code will allow you to access your account. 
10. Once you have captured and recorded the recovery code, check the box that says "I have safely recorded this code;" then, click Continue. 
11. You are now enrolled.
