I'm not familiar with the FIDO API so I am wondering if there is a way to use/"blip" a NFC key (YubiKey) as authentication method on a website implementing the FIDO API running on an Android device (in chrome browser/custom tabs)? How is this enabled in that case?
It seems the Google native FIDO2 API supports fingerprint and screen lock, but cannot really find any specific info about NFC keys in this case either.
