Proposed Features
  1. Hardware Key Login
Description: Enable FIDO2/U2F hardware keys for 2FA or passwordless login.
Implementation: Support YubiKey, Titan, etc., with fallback options (e.g., authenticator codes).
Benefits: Phishing-resistant authentication for secure access across platforms.
  1. Passkey Authentication
Description: Integrate FIDO2 passkeys for passwordless login via hardware keys or device biometrics.
Implementation: Support device-native passkeys (e.g., Windows Hello, Face ID) and key-based passkeys.
Benefits: Simplifies login while maintaining high security.
  1. Encryption Key Management
Description: Store XSalsa20 encryption keys on hardware keys for zero-knowledge security.
Implementation: Support secure key storage and rotation, with encrypted recovery codes.
Benefits: Strengthens encryption by keeping keys off vulnerable devices.
Technical Considerations
Use FIDO2/U2F standards for compatibility.
Ensure cross-platform support (web, desktop, mobile).
Protect against key cloning and align with S3Drive’s quantum-resistant encryption.
Benefits
Phishing-resistant, passwordless authentication.
Secure encryption key storage.
Alignment with industry trends (e.g., Apple, Microsoft passkeys).
