In this case of getting reports from users, the 1st thing the admin would do is login to their Microsoft 365 Admin center and look under MFA (multi factor authentication), and then they’d see - it actually still shows as “Disabled” for each and every user! We’ve heard from the administrators of Microsoft 365 hosting accounts that say their users report being asked to set up Microsoft Authenticator app even though that admin person themselves didn’t know that would happen and hadn’t turned the MFA (also known as 2FA) on yet. If you’re one of the “ Admins” for your 365 hosting, follow along with these steps we’ve put together below to show you what’s going on. If you’ve had a Microsoft 365 hosting account setup recently for email at your company and your users are being prompted to set up authentication codes - but you looked and the MFA in your 365 admin shows as “Disabled” - then follow along here and we’ll show you why.
