@lunareclipse I thought if CTAP2 works over USB, this NFC workaround should work too.
In any case, the cheapest key you referenced (T2F2) is at least 6 years old. Newer ones have PGP, PIV and 300 passkeys in addition to NFC. And I found a working promo code (7% off) here if you want to get it cheaper- https://www.mydealz.de/gutscheine/token2-bio3-der-erste-biometrische-fido2-sicherheitsschlussel-mit-dual-usb-ausb-c-schnittstelle-und-ios-fingerabdruckverwaltung-2594368
the discount is active and works on any product, so you can use it with the one you originally intended to buy as well
@lunareclipse dont give up on Android+NFC
