Hotmail one time password

[brums evil twin]

This is nothing to do with Hotmail issues over the weekend.

I am getting quite a few emails saying here is your one time password - Someone is trying to get into my email I guess.

I have updated the password and turned on using the authentication app, is there anything else I need to do to prevent a hack???

Thanks

MFA is all as far as I am aware. Someone tries to enter a password every 2hrs on my Hotmail account according to the activity logs.
