Hello and Welcome to the Microsoft Community!
My name is Levi. I am an independent advisor and fellow Microsoft user like you. I have no affiliation with Microsoft and do not have access to your data.
I believe what you're seeing is a login attempt that wasn't made by you, right? Unfortunately, data breaches are not uncommon, and you may encounter situations like this.
Your best option is to secure your data as thoroughly as you can. Change your password for your Microsoft account and make sure to create a strong password that you don't use for any other accounts. Additionally, add your phone number and confirm it. It's also important to strengthen the password for your secondary email.
Enable two-factor authentication for enhanced security. While these steps can help protect your account, you may still experience occasional login attempts.

I hope this helps.
