Microsoft Authenticator keeps sending log in requests when I'm not trying to log in.

Hello @ShaneColeman-6069,

It appears that you are experiencing unauthorized sign-in attempts that are repeatedly triggering Microsoft Authenticator notifications.

1 - If You Are Using a Personal Microsoft Account

You can use any of your aliases to sign in, and you can select any of them for sending and receiving email. Verification codes sent by email can only be sent to your primary alias or another email address added as a verification method. Therefore, you can change your primary email address while you still able to use it as alias email. Prevent from unknown sign-in attempts.

You may follow the steps in the Microsoft KB below to add a new alias: Change the email address for your Microsoft account | Microsoft Support

To help stop unauthorized sign-in attempts, you can:

• Create a new email alias (a random string)
• Set the new alias as your primary sign-in email
• Disable sign-in access for the old email alias

As a result: Unknown users will no longer be able to attempt sign-ins using your old exposed email address.

2 - If you are using Business Account

If you are an end-user, you can reach out to your Global Administrator or IT Support team to further improve account security and help prevent repeated authentication notifications. They can support to change your primary email address and keep the current email as alias so you can keep send and receive email from the alias email address. For more information on how to change alias: Add another email alias for a user - Microsoft 365 admin | Microsoft Learn

To review your account activity, you can go to https://mysignins.microsoft.com/ . Then select Recent activity from the left pane

If you are an administrator, you can check the sign-in logs in https://entra.microsoft.com/

1. Navigate to Users > All users. 
2. Search for your account and open the Sign-in logs. 
3. The sign-in logs will display all login attempts, including whether they were successful or failed. You can review the status messages in the event details for more information. For example:
