When trying to sign in to the Microsoft Authenticator on my new phone I get a "That Microsoft account doesn't exist." Error even though im currently using that account to make this question and use it daily to authenticate my log in for my schooling on this phone.
Hi JenkauskiDarian,
It's probably because it's a work- or school account.
You can add these by going to https://aka.ms/mfasetup
You'll then get a QR code that you can scan with your phone with the Authenticator app.
I hope this helps.
