## Description

Passkeys bound to your device — not replicated to a cloud. Private keys live in the Secure Enclave, gated by Face ID or Touch ID. No account, no sync, no tracking.

Titanium Passkey is an offline FIDO2 / WebAuthn credential provider for iPhone, iPad, and Mac. Every private key lives inside the Secure Enclave and never leaves it. Every sign-in is gated by Face ID or Touch ID, enforced in hardware.

WHY TITANIUM PASSKEY?
• Passkeys bound to silicon — never replicated to a vendor cloud you don't control
• No account, no sign-up, no subscription — install and use
• Works with every passkey-capable site: GitHub, Google, your bank, self-hosted apps
• A stolen phone signs nothing — biometric enrollment gates the private key at the hardware level
• Zero telemetry, zero analytics, zero tracking SDKs in the binary
• Sign in on any desktop — Windows, Mac, Linux, Chromebook. On the browser's passkey prompt, choose "Use a Device Nearby" / "Other Options" and scan the QR code with your iPhone. Your phone stays the authenticator; the desktop never sees your key.

HOW IT WORKS
Enable Titanium Passkey under Settings → Passwords → Use Passwords and Passkeys from. When a site requests a passkey, iOS routes the challenge to the extension. The extension wakes, Face ID or Touch ID unlocks the key inside the Secure Enclave, the assertion is signed on-chip, and handed back. You're signed in.

WEBAUTHN SUPPORT
• ES256 (COSE -7) over WebAuthn — the baseline every passkey-capable site supports
• PRF extension (hmac-secret) for encrypted data binding
• Conditional mediation — silently offer passkey sign-in without interrupting the user
• Fast authentication — skip the picker when only one passkey matches

STORAGE & KEYS
• EC P-256 keys created with kSecAttrTokenIDSecureEnclave — not extractable by the app, iOS, or Apple
• Gated by biometryCurrentSet + privateKeyUsage — re-enrolling Face ID invalidates keys
• Keychain marked AfterFirstUnlockThisDeviceOnly — excluded from iCloud, iTunes, and Finder backups
• Optional multi-device tier for iCloud Keychain sync, off by default, trade-offs explained in-app

PRIVACY
• The Credential Provider extension has no network entitlement — it cannot reach the internet
• No account, no email, no cloud
• No telemetry, no analytics, no ad identifiers
• Attestation uses the 'none' format — we don't uniquely identify your device to relying parties
• Anonymous crash reports only if you've opted in via iOS Settings

No subscriptions. No in-app purchases. Just passkeys, bound to silicon.
