WebAuthN, Security, the TPM, FIDO, and Multi-factor Authentication

In a world where security is top of mind, I wonder why Norton and its parents have not figured out how to integrate FIDO, WebAuthN, and CTAP into the authentication mechanism I use to sign in to my PC.

Yes, I see strong use of p[passwords, and you use the biometric capabilities of Mobile phones with the Secure Element, EUICC, KNOX, or Secure Enclave. Why are you not trying to use the TPM that sits inside most of our Windows 10 devices?
