Same exact situation for me. Even with brand new password unused anywhere else.

it’s been happened to me for the last week. I don’t know what’s going on. I’ve changed my password. I’ve changed all of my backup emails and even the phone number. I’m at the point now where I’m going to look for a different authentication app because this is ridiculous I had to turn off notifications on the app because I’m getting multiple ones an hour so if it’s a hack, Microsoft should release some information about it. If it’s an error, they should also release some information.

Hi,
If you are receiving repeated Microsoft Authenticator sign-in requests that you did not initiate, it may indicate that someone is repeatedly attempting to sign in to your work or school account. Changing your password helps secure the account, but it does not prevent others from continuing to submit sign-in attempts using your email address.

To better understand the situation, could you please provide a little more information?

1/ Does the sign-in request display any details such as a location, application name, or device?

2/ Are you able to see any unfamiliar sign-in activity in your organization’s account activity or security logs? You can follow the instruction here: View your work or school account sign-in activity from My Sign-ins | Microsoft Support

3/ Are the prompts appearing on a single device or multiple devices?

4/ Did this start recently, or has it been occurring for an extended period?

If this is a managed work or school account, I also recommend contacting your organization’s IT administrator so they can review the Microsoft Entra sign-in logs and determine whether these requests are coming from failed authentication attempts or another source.

Once you provide the additional details above, I’ll be happy to help investigate further.

Changing my passord did not help. There are no other details on the sign-in requests which are coming straight to my iPhone only. I have a personal account. This only started a few weeks ago.

Hi,

Thank you for the additional information.

Since this is a personal Microsoft account and changing the password did not stop the prompts, it is possible that someone is repeatedly attempting to sign in using your email address. In that situation, the sign-in requests can continue even though they do not know your current password.

I recommend reviewing your recent account activity here:

Recent activity page

Please look for any unfamiliar sign-in attempts, locations, devices, or failed sign-in events.

If the requests continue and your account activity does not show any successful unauthorized access, one additional option is to create a new sign-in alias and make it your primary sign-in address while preventing sign-in with the old address. This can significantly reduce unwanted sign-in attempts because the old email address is no longer accepted for authentication.

You can learn more about account aliases here:

Microsoft account aliases

Please let me know what you find in your recent activity page, and whether the sign-in requests continue after reviewing your account security settings.
