Question about Microsoft Account Sign-in Verification

Microsoft has been pushing passkey lately so I revisited my Microsoft Account. Based on the security settings, you can have

Sign-in Method - what you use to login

• Password
• Security Key or pin or biometrics
• App - Microsoft Authenticator.

Veriify method or 2FA. N ote that MS does not allow security key authentication.

• SMS - supposedly removed now for new users
• Email
• TOTP
• Push notification

There is an additional setting for two step authentication, which is turned on for me. The two step is for 2FA.

My thought was to remove the SMS and the email, but Microsoft seems to post a warning against doing that in this link: "If you request removal of all security information in your account, the account is put into a restricted state for 30-days.". I poke around and it appears to mean if you remove your email and phone method. My guess is Microsoft is certain that if you remove your email and phone , they have no way to identify you. Frankly, I don't understand why they can't just make this a required field elsewhere and allow the user to not use it as a verification method. Currently, it appears that if I remove both method, my account may be restricted. I am not going to try to to find out. Has anyone actually tried removing both email and SMS? Note that SMS may have been removed for new accounts.

Microsoft does allow you to remove the password. While I did like that password can be removed, it could not be done because then I can't use the account to login into services like RDP to a server. As a result, I had to retain thee TOTP or the push notification. As mentioned before I still have to have SMS or email as a backup. What is the min method you are using to login to minimize attack surfaces?

Thanks

As far as I know you have to have an email associated with it, but I am no expert.

The experts should be here shortly to help.

Microsoft sign in is pretty crazy, some times it works and sometimes it does not.

I now use the pin (passkey) to sign in at works well.

I could never get the Microsoft Authenticator app to work after multiple reinstalls on Android phone.

But it works for other accounts I have, not Microsoft.

Very odd.

I have had to change my Microsoft password several times becuase microsoft sais my passwrd was not correct.

Don get me started on my Unraid mapped drives that took hours because Windows said my credentials were wrong.

Thanks in the past I did try to remove both years ago but Microsoft required that I have either an email or a phone.

You can set up two passkeys (e.g. Windows and Android) plus a recovery code (stored offline) to eliminate everything else.
