Whilst trying to change the login Pin, I was asked to verify myself through an old email address. Although I can still received emails to this old address, I no longer want to use it. How do I go about removing this out of date email address.I checked in my account but am unable to fine it

FireFox Account Sign in Authentication Issue

I don't have an answer, but maybe something here can help. (It looks like maybe the time sync for codes is off. It's in one of these posts.)

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.

 

Child Account 2 factor authentication not sending code

My child's Microsoft account is trying to send him a code. The email option is to my old hotmail account which not longer exists. (moved to outllook). My cell number has the correct last 2 digits and when I enter the full 4 digits it tells me they are unable
to send code to that number. I am stuck with no way to do the authentication. Suggestions on how to receive the code would be great. Thank You.
