Passkey basics
Passkey is a cryptographic key pair. Public key on website, private key on your iPhone (Secure Enclave). Authentication = website challenge, iPhone signs with Face ID, sends signed challenge back. No password to phish.How to enable passkey on a service
Most services: Account Settings → Security → Add Passkey. Service shows QR code on screen. iPhone scans → uses Face ID → passkey created. Passkey synced to iCloud Keychain → all your Apple devices.Security advantages over passwords
Passwords can be phished, leaked in breaches, reused across sites. Passkeys are unique per site, cryptographically signed, never transmitted. Cannot be phished — phishing site can\'t trick you into signing for real site. Eliminates entire class of attacks.Cross-platform via QR codes
Need to use passkey on Windows or Android? On the other device, choose 'Use a different device'. iPhone shows QR code. Scan with iPhone — Face ID — done. Passkey stays on iPhone, just authenticates other device.Recovery + iCloud Keychain
Passkeys sync via iCloud Keychain. Lose iPhone? New iPhone signs in with Apple ID + iCloud Keychain restores all passkeys. Apple Account is the master credential — protect it with Stolen Device Protection (iOS 17.3+) and hardware key.Services with passkey support
