Authenticator App - can't remove greyed out account

Hello all,

I'm stuck in a strange loop using the MS Authenticator App. I'm one of the admins at my school and I've registered my phone via https://account.activedirectory.windowsazure.com/securityInfo using the MS Authenticator App.

I wanted to create a manual for my colleagues so I removed the app from my phone (without deleting the account first, because I assumed that it would be deleted when the app is removed), redownloaded and reinstalled it so I could show them step by step what they should do and how to use the app.
However, my account was never removed when I uninstalled the app and is greyed-out, so I can't edit or delete it.
When I then try to change the MFA settings in my Active Directory User account, I can't access the 'Additional security verification page' or the 'Securty-info page', because it tells me that I should approve the sign in request from my app, but the app tells me it cannot process the request from the work or school account and I should remove the app first from the MFA registration page... So I'm stuck in a loop, because I can't access the MFA registration page and I can't approve the sign in request from the app.

I've tried multiple possible solutions, like checking if there is a MFA policy in Azure for our school, trying to remove my phone from devices in the Azure Users panel, ...

What might be causing this problem and how can I fix it?

Thanks in advance!

Ris

    Hello all,

    To remove a greyed out account on the MS Authenticator app, you must delete the account to the smartphone.

    For example, you want to remove the foo@zamir1 .com account to the ms authenticator app
    For Android :

    • You edit your smartphone parameters --> account
    • You have to see an entry "professional account" foo@bar.com
    • Delete this account
    • Return to the MS Authenticator app, the "evil" entry has disappear !

    Hope it works for you !

    I have a Xiaomi Android phone. I finally located the Settings/Accounts & Synch/Authenticator where the work account is stored. I deleted the work account there and pressed the Synch button and the obsolete/greyed out work account in Authenticator is gone!
