Hi @David Iluz ,
Welcome to our forum!
According to your description, i notice that you are worried about your account security. It's suggested that you could go to the Recent activity page.
If you're concerned that someone might have access to your account, we strongly recommend that you change your password and update security settings. You can do that on the Security settings page, where you can also remove all trusted devices. To learn more about account management and security, see Security basics.
More information: Check the recent sign-in activity for your Microsoft account.
Hope to help you!
