According this page
https://support.google.com/product-documentation/answer/14343500#zippy=%2Cearlier-version-release-notes%2Cjanuary, NFC Authentication is meant to work natively for CTAP2. Do a search for "nfc" or look at Security & Privacy under January 2026. It states authentication via NFC should work for CTAP2.
I have tested on multiple different Android devices, newer ones, older ones, Galaxy S25s and the latest Pixels. The NFC option does not appear for any of them. The phones are all up to date for both the "Google Play Services" app. The "Security update" is on 5 February 2026 and the "Google Play system update" is on 1 February 2026.
The fact that Google still haven't addressed this after three months is completely ridiculous. This is a feature iPhones have had since 2019
