Do a search for "nfc" or look at Security & Privacy under January 2026. It states authentication via NFC should work for CTAP2. Except it doesn't. At all.

For the record, this is a feature iPhones have had since 2019. The fact that it's been 7 years and Android don't have it is ridiculous. And then when they say they have it, they don't! And apparently no one has noticed.
