Accessing Microsoft Teams using organizational or personal credentials
I can't sign in because my account says it need me to approve the sign on in the Authenticator app. HOWEVER, the sign on for the Authenticator app is ALSO saying I need to approve the sign on in the app. So I can't sign in to approve it without already being signed in. SO I am stuck in an infinite loop of it asking me to approve a sign in on my account in an app that I can't sign into without already being signed in!
If you are on a work account, you most likely need to have your administrator reset your Entra MFA (multifactor authentication) so you can re-establish Microsoft Authenticator on the new device.
Kind regards.
