This project provides a workaround that effectively brings CTAP2-style capabilities to NFC keys on Android by acting as a Passkey provider / Credential Manager service, handling the correct communication with your FIDO2 key or card over NFC.
Requires:
- Android 14+ (API 34)
- A FIDO2-compatible security key or card
Based on Authnkey project from Michel Le Bihan
