Windows 10: Managing 2FA Trusted Devices

When I signed in after turning on 2 factor authentication, 2FA, for my Microsoft account I was prompted with an option to trust my device and avoid having to enter the 2FA code when you login to my MS account or MS apps. My questions are 1) how do you determine which of your devices are trusted and 2) how do you un-trust a device and force the use of 2FA for login. I am using Windows 10 Pro Version 20H2.

Hello James,

Have you already synced this My Book1140 with his Microsoft Account?

Suggest you to login to your Microsoft Account and check whether this My Book1140 is listed as a trusted device. If you have already added this as a trusted device in Microsoft Account then it will get automatically synced if you use the same Microsoft account
in some other devices.

 

Bitlocker and Trusted Platform Module problems

We appreciate the screenshot you sent.

This issue usually occurs because the Trusted Platform Module (TPM)
uses the manufacturer driver and not the Windows built-in Trusted Platform Module driver.

To resolve this, you can manually uninstall and reinstall Trusted Platform Module. To do so, see the steps below:

• Open Device Manager on the device on which you are experiencing the issue
• Uninstall the Trusted Platform Module driver.
