Hackers keep getting prompting me for a code on authenticator
Is there a way to help prevent this?
Yes. Create a Login Only Alias and disable Sign-In for your current email address. Then, if all the Bad Guys have is your old email alias, they get "This username has been turned-off for sign in" at the very first step of the logon process and can not continue.

This makes no difference. I have done this, and yet I still get authenticator requests for the old email alias. I changed the password. I forced sign out of all sessions multiple times. I created a new email alias that has only been used for his, I moved to passwordless sign in, and yet I still get authenticator requests. None of the solutions proposed stop these messages being delivered to authenticator which leads me to believe it must be a MS issue.
