Which two are required to use passkeys on iPhone?

To use passkeys on an iPhone, having iOS 16 or later installed and enabling iCloud Keychain is essential. Passkeys are a modern solution to password management that enhance security by allowing users to authenticate without traditional passwords.

With iCloud Keychain turned on, users can securely store and manage their passkeys, which are then synchronized across their Apple devices. This ensures that passkeys are easily accessible and maintained in a secure manner. iOS 16 introduced improved support for passkeys, making it necessary to have this version or newer to access the feature.

The combination of using iOS 16 or later with iCloud Keychain allows users to fully leverage Apple's security ecosystem and benefit from the convenience and security that passkeys provide. This integration is vital for ensuring both the ability to use passkeys and optimal security practices.
