Microsoft Authenticator | Unknown Devices Linked to My Account

Question

I am reaching out to seek assistance regarding an issue I encountered while signing into Outlook via the browser and using my authenticator app. During the sign-in process, I have the option to view which devices the sign-in request is being sent to:

Unfortunately, several devices appear that I do not recognize:

I have already taken all necessary steps to verify my device. However, I do not see any devices listed under the "Devices" section on account.microsoft.com, including the device I regularly use for authentication.

Additionally, I have not found any option in the settings of the Authenticator app to check which devices are set up for authentication. It seems that these devices are not listed anywhere.

I am seriously concerned about the security of my account, as I cannot track which devices are linked to my authentication. I would greatly appreciate your assistance in identifying these devices.

Thank you for your support.
