Add WebAuthn for authentication and 2FA

Would you mind adding WebAuthn (https://webauthn.io/) to your services? As most browsers support it, you would be able to offer passwordless authentication and 2FA using all kinds of solutions (TouchID, FaceID, YubiKey, Hardware Wallets, Windows Hello, etc.).
