Microsoft 365 Login Microsoft 365 Admin Error: Step-by-Step Fixes

This guide walks you through mfa & verification issues using Microsoft-supported steps first, with WPS only where it genuinely helps.

Problem Description: Login Microsoft 365 Admin

I can't login my Microsoft 365 admin account because it now has forced MFA and the ONLY option is Microsoft Authenticator which has not been set up and there are no other options. I call for support and can't open a case via IVR because it is forcing me to aka.ms/prosupport which requires me to login with an admin account. I was able to change the password successfully because I can send it to the backup email I set up to send a code to, but don't understand why the same options isn't available for MFA. I login and then prompted for either of these options. As I said, I have not yet set up Authenticator for this account nor any of the users in this account. Then when I click Use a Verification Code a prompt for a code from Authenticator.

Working with WPS Office: WPS as a Local Alternative
