Accessing Microsoft Teams using organizational or personal credentials
This isn't helpful because I am the admin. There's only one person on my 365 account, that's me. I can't change the 365 sign in settings on my browser unless I have a code from the authenticator app, but I can't add the account to the authenticator app without signing in to the account, which I can't do unless I have a code from the authenticator app. It's a loop just like described above.
