Microsoft MFA (How To) Enroll a Phone Number for Voice Call from Sign in Prompt
This article provides instructions for setting a phone call (voice call) as a primary authentication method from a sign in prompt.
With Microsoft MFA, users have the option to enroll a phone number to use as an authentication method. However, because Teams is Microsoft authentication dependent, you MUST NOT submit a Teams phone as a verification method. A mobile phone number or home phone number (landline) may be used as an authentication method. With phone call verification during Multi-Factor Authentication, an automated voice call is made to the phone number registered by the user. To complete the sign-in process, the user is prompted to press # on their keypad.
