What are the phone numbers Microsoft Authenticator may contact users from? RRS feed

  • Question

  • I'm looking for a list of phone numbers that Microsoft uses to call users for MFA. Our users are used to one particular US number which we recognize, we have suddenly new numbers, including numbers from India calling our users.

    I need a list of all phone numbers.
