wait a second, what? If I use the same email for another account, I could get randomly locked out from some other account. I just checked my app., there are 2 different emails for 2 entries, other entries are provider specific. Is there a good way to migrate from MS Authenticator and what options do I have? One of the entries without the Issuer correctly set is Outlook.com itself. WTF!
