Hello,

I have noticed that when signing in to Outlook through the browser using my Authenticator app, I not only have the option to authenticate myself but also to see which devices the sign-in request is being sent to.

When I click on this option, a list of devices appears, none of which I recognize. I only own one device (an iPhone), for the sign-in requests. I have already checked my security settings but cannot find these unknown devices there. My device is also not visible. This concerns me as I want to ensure that my account and data are protected.

Could you please explain what these devices are and how I can obtain more information about them? Is there a way to identify these unknown devices or verify if they are indeed associated with my account? I would greatly appreciate your assistance, especially regarding the security of my account.

For reference, please see the attachment that lists the devices.

Thank you very much in advance for your help!

Best regards

    These could be devices you previously used to sign into your account but are no longer in use. And they will remain till you remove.

    Visit account.microsoft.com

    Look for "Devices"

    Remove any devices you do not recognize or cannot verify.

    Change your Microsoft account password immediately

    Verify two-factor authentication is enabled.

    Open the Microsoft Authenticator app.

    Go to settings and ensure only your current device is set up for authentication.
