> U2F via NFC is a great way to authenticate on Android Unfortunately as far as I know only Yubikey NEO and Fidesmo card support it with Fidesmo being practically not usable. From https://www.fidesmo.com/nfc-u2f-android/ https://www.fidesmo.com/nfc-u2f-android/ : > Google’s own account security website, that on desktop allows you to register U2F devices, says that the feature is not compatible with the Chrome browser on Android. The account security site on GitHub seems to support the feature is a bit better. When pressing the button to add a token to the account it properly launches Google Authenticator to register the U2F device. When tapping the card and returning to the GitHub site however it doesn’t seem to have registered that anything has happened.
