I keep getting Authenticator requests that are not mine. I keep denying them but Security Acitivity is not showing that I'm denying them.

Answer 1

If someone has your email address they can go to Microsoft online, use the forget password to trigger a verification request. They obviously don’t have your password or even try to enter your password so you won’t see any failed attempts in activity.

Then, take one step further - Go to your Microsoft account online https://account.live.com> Sign in > Your info > Sign in preference. Add an alias - You have two options here:

Create new: this will allow you to use the native domain outlook.com to create a new alias.

Add existing: this will allow you to add a 3rd party email address, such as yahoo, gmail, as long as they are not already associated with another Microsoft account.

Once added, make this new alias your primary alias, do NOT delete the old alias. Then at the bottom, click on "Change sign in preference". On the next page, uncheck the box for the old alias. This means, from now one, the old alias cannot be used to sign into your Microsoft account, but it can be still used to receive emails, etc.
