Setup using text messages
1. Go to https://aka.ms/mfasetup to set up your phone as the second authentication factor.
2. If you would like to use text messages instead of the Microsoft Authenticator mobile application,
choose the ‘Text code to my authentication phone’ or ‘Authentication phone’ from the drop down menu.
3. Then follow the steps to add your phone number. You may receive text message with a 6 digit verification code to verify your phone number.
4. Once verified you can select the blue ‘Save’ or ‘Done’ button.
