Constantly getting requests for sign in to my email address from another country on Microsoft Authenticator

Question

Hi,

I live in Australia, and change my email password regularly.
I am constantly getting requests to log in via Microsoft Authenticator from the United States. These are not me. You need to do something. If my account gets hacked, I have done everything I can do to avoid this. Do not tell me to change my password again. You need to set my account to only allow log ins from Australia.

Stop unsolicited Authenticator notifications - Mute

From a suggestion by Reddit user arnoldstrife

One possible workaround is to simply disable Authenticator notification on your phone. Then when it's you who is trying to sign-in:

• Open the Authenticator app on your phone.
• The "Enter number", "Enter code" or "Approve request XXXXX" prompt will be waiting for you.
• Continue with the authentication just like you normally would.
• (You may see a nag about turning on notifications).

Each Sign-In session generates a different number or code. As long as you ensure that the number or code you enter, or the request you approve, matches what you see on your screens, you will never allow the wrong session.

Disable Authenticator notifications from the App

If you wan to stop the Bad Guys from even trying to logon to your account.

All they need is an email with Sign-In enabled. They do not need your password or any other security info to generate an Authenticator notification.

The only way to stop any login attempt is a Login Only Alias and disable Sign-In for your current email address. See the Answer "Login Only Alias" by "Hornblower409 on Feb 27, 2026" in

This includes the crucial step of changing your default Send From email address so that you don't leak your new alias into the wild.

Answer 2

I'm sorry to hear that you're experiencing this issue. Login attempts typically occur when your email address has been leaked on the dark web. As long as these attempts are unsuccessful, your account remains safe. To prevent this, create a new alias for your account and set it as the primary. Then, configure your account settings to require sign-in only with this new identifier.

1. Log in to your Outlook email account: Outlook.com or https://account.live.com
2. Under your profile photo, click on "My Microsoft account."
3. On the new page, click "Your info" and locate the "Account info" section.
4. Click "Sign-in preferences" and, under "Account aliases," add a new email address or phone number that is not publicly known.
5. Ensure it’s a valid and accessible contact.
6. After adding, select "Make primary" to set this new email or phone number as your primary sign-in.
7. Scroll to "Change sign-in preferences," uncheck your current Outlook email address, and check the box for your new login method.

Important: DO NOT delete the current/old email address

This will keep your email account active for sending and receiving messages while preventing login attempts.
