How can I stop all the unauthorized login attempts from around the world?

Dear KE_86,

Thanks for using Microsoft Product and posting in community.

I'm sorry to hear about the unauthorized login attempts on your email account. It's really disturbing to receive verification login messages from different parts of the world every day, and it's good to know that you've enabled double verification, so your account is definitely safe, and rest assured that hackers will never be able to log in without your authorization.

Of course, in addition to double verification, you can also download and install a Microsoft secure authenticator, because this authentication method hackers can not enter or try your password, this process cancels the process of typing the password, you can click here to set up!

I know you don't want your account to be constantly trying to log in, I have a more niche method here that may be useful to some people, if you don't find it cumbersome you can also try to use it:

In order to solve this problem, if you are able to log into your account properly you can click this link to log in your Microsoft account, click [Your Information]-[Account Information]-[Edit Account Information], you can add an alias for your account in this interface, please note that due to the potential risk of your current account, it is best to create an alias that does not require outlook/Hotmail authentication and set the added alias as the primary Alias. You can then click [Change Login Preferences] below to uncheck the checkbox in front of your old account, which will make it impossible to log in with your old account name, thus effectively stopping hackers from constantly logging in. Please remember to keep your new account alias. You will also not be able to log in to your account with your old account name. In our tests, you were still able to receive emails under your old account name. 

Note: Usually, hackers don't attack the same account consecutively, the attack will have a duration and if your account doesn't exist for a long time, the hacker's automated attack script may no longer try to access it. You can reset the original name back to the main alias after a certain period of time, usually we recommend users to hide it for 3-5 days. I hope my reply was helpful!

 If you have any other questions, please feel free to reply to me at the bottom of this post!

"About Microsoft Authenticator - Microsoft Support" does not work. I get access denied or similar. And I too have been getting absolutely bombarded with login attempts. I have had to change passwords twice today.

Keeping Hackers out of Microsoft accounts - Outlook Tips

This is exactly how mine is! Started one December 8, 2024 and has been 15+ attempts from all over the world every single day since!

Exact same day as mines was successfully hacked into, I recovered my account and since 01.01.25, I have a list similar to yours of unsuccessful login attempts. They took over my social media, locked my accounts and have impersonated me alongside bitcoin fraud using my social media. Insane that all these attempts aren't picked up on by Microsoft!
