Windows 10: Authenticator app login issues

I lost access to my authenticator app and can not gain access back. I also cannot do a backup due to having a new phone and apple id. How can I regain access?

Windows Microsoft account authentication

I have a valid Microsoft account and a Windows 10 PC with Hello/PIN account login enabled. I also have the Microsoft Authenticator app installed on an iPhone and configured for the Microsoft account. Additionally, I have two step authentication configured
for the Microsoft account. With all of that said, I have become very exasperated while trying to unravel the various authentication paths (and their security implications) through this multi level login security scheme. I find the associated account security
documentation to be woefully inadequate. Thus, I would like to pose the following list of questions for starters.

1. Does Windows Hello/PIN amount to a two step verification login procedure for my Microsoft account?

2. Does approving a Microsoft Authenticator login attempt (without two step verification explicitly set up)

amount to a two step verification login procedure for my Microsoft account?

3. Does approving a Microsoft Authenticator login attempt (with two step verification explicitly set up)

amount to a two step verification login procedure for my Microsoft account?

4. If answers to both 2 and 3 are yes, then what does explicit set up of two step authentication do?

5. Does a coherent, comprehensive document explaining Microsoft account security configuration exist somewhere?

6. If the answer to 5 is yes, wherer is it?

Thanks in advance.

 

Microsoft Authenticator app issue

When I try to sign in it asks for a code from my Authenticator app to login. I forgot to register Authenticator app during my login screen. Please help for support.

 

New Microsoft Authenticator app version for Android and iOS - Sept. 3

Two factor authentication (TFA) is easy, convenient, and secure when you use Microsoft Authenticator. Use your phone, not your password, to log into your Microsoft account. Just enter your username, then approve the notification sent to your phone. Your fingerprint, face ID, or PIN will provide a second layer of security in this two step verification process. After youve signed in with two factor authentication (TFA), youll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more.
