Office 365 MFA enforcement.

Question

Hi, I just received an email saying that Microsoft is going to enforce our tenant to use the Microsoft Authenticator app. We currently have a federated domain with DUO Security as our Authenticator. I am really hoping that we are not forced into using Microsofts Authenicatior. Currently, we are using a push notification instead of OTP and we can control a lot of things with DUO Authentication. Including Zero trust devices.

Answer 1

I think it may be referring to registration campaigns. Please check your settings as seen below and ensure All users is not selected:

Protection > Authentication methods > Registration campaign > Authentication method.

Hope this helps with the information given.
