Authenticator mobileapp

Hello @Anders Eriksson

Receiving multiple unauthorized sign-in requests from various international locations can certainly be concerning.

This activity occurs when your email address or username becomes visible to automated scripts on the internet. When an unauthorized sign-in attempt is made using your email, the system automatically routes the notification to your Microsoft Authenticator app as part of its security design. By consistently denying these requests, you are taking the right steps to help protect your account and prevent unauthorized access.

In this case, I recommend taking the following steps to further strengthen your account security and prevent repeated notifications based on your account type:

1/ If you are using personal account:

You can set up an additional sign-in alias. These options help reduce unwanted sign-in attempts and provide an extra layer of protection.

-Sign in to your Microsoft account 

• Go to: https://account.live.com/names/manage

-Choose “Add email” 

• Start adding a new alias (do not remove anything yet). 

-Create a new email alias 

• Use a strong, hard-to-guess address (e.g., random string). 
• Set it as your primary login email 

-Make the new alias your main sign-in address. 

-Disable login for your old email 

• This is critical, it blocks attackers from using the old address. 

-Remove the old email alias if you no longer need it (Optional, last step)
