Someone has been trying to hack into my MSFT account for years. I constantly get the notifications. I can not see where they are trying from (unlike some other services that give you info about failed login attempts) nor add more security measures. I worry one day I will accidentally hit "Approve" or they will guess the 6 digit code they have tried thousands of times.

The fun part is that you can't disable OneDrive. No matter how many times I turn it off it always keeps turning OneDrive back on to put my private data in the cloud for the attackers. Of course I can't block the methods that are obviously under attack either.

And the lack of a login history view means I have no way to know if they were successful yet. Support has never been good (for legitimate users) and is basically non-existent with AI now.

You can disable the email you use publicly as a login email.

I would recommend you look at some other guides before you do this but the gist is My Account > Your Account > Manage Account Information. Then you can add a new email that you do not share as your primary login email, and disable login from the email you use to send emails.

I have about a dozen email aliases associated with my Microsoft account. On the "Your info" page, under "Account info", one of them is described as "The email address you use to sign in to your Microsoft Account".

However, I can use any of them to initiate a login attempt. I have my account set to passwordless, I don't know if that is relevant (every login attempt triggers an MFA prompt).

If I click on "Edit account info" I am taken to a page where I can choose which address in the "Primary", but given that ANY of the aliases can be used to intiate a sign-in, I don't see any benefit in changing that.

EDIT: I wasn't being adventurous enough. The option to change which aliases can be used to sign in is under (surprisingly) "Sign-in preferences".

In my defence, that page wasn't loading properly in Firefox with all my privacy add-ons enabled. I was able to access it in Edge.

EDIT2: I've changed my primary alias to a newly created one. If I am still able to sign in OK in a couple of days, I will disable the old primary for sign-in. I hope I don't live to regret this!

Re Onedrive, as someone who left windows ages ago: Why not just create folders outside your user home? Create some junctions from the inside. Then onedrive gets to sync only your desktop wallpaper and any random stuf apps drop in there, and your real data is safe outside its reach.

I think the best defense against this is to delete the Microsoft account and enjoy a better life. (Unless, of course, you need it for Minecraft.)

The correct thing to do in this scenario is to create a new random login alias on your Microsoft account, make it the primary login alias, and disable login for the all other e-mails tied to the account.

You can view the recent activity on your Microsoft account @ account(dot)live(dot)com/Activity

Would show any logins or security info updates etc

Those login attempts which trigger 2fa app does not generate a log entry if unsuccessful. Only attempts with username/password does. For some strange reason.

So there is no way to flag them as malicious and if you accidentally accept, then it’s already too late.

Pretty annoying setup.

I have the same issue. It’s absolutely stressful. Id also love some way to mark them as malicious.

I know they’re always changing things but I’m 99% sure one drive can be disabled with a checkbox either in “turn windows features on or off” or via group policy editor.
