iCloud Keychain ensures your passkey's private key is always end-to-end encrypted, no opt-in required. Its automatic and secure. 

With Keychain's design, you don't need to sacrifice availability for security. ⚡️

Leveraging the secure enclave, iCloud Keychain passkeys offer hardware-level security. The passkey is never exposed outside of the secure enclave. All signing actions occur within the secure enclave of your trusted device. 🔒

Your private key is NEVER exposed in memory!

Hacked iCloud account? Also lost your phone?

Your data still stays safe! The passkey is secured by your biometrics like FaceID or TouchID, which means that in-personhood is required to use the passkey.

Apple can NEVER access your passkey. iCloud hacked? No sweat. Apple employee bribed? 🤷‍♂️  Security maintained.

Even with this security, you can still recover your passkey even if you lose ALL of your trusted devices! Keychain safeguards your data even in extreme scenarios

Usage notes!
To use passkeys, ensure you're on iOS16, iPadOS16, macOS13, or tvOS 16 (or later) with iCloud Keychain and two-factor authentication turned on.

Further, I HIGHLY recommend you add a Recovery Contact (or 2 or 3!) to your iCloud account! 🫂
