Your iCloud Keychain data is encrypted with AES-256 bit encryption, and Apple cannot access your passwords or personal information.

Works automatically across iPhone, iPad, Mac, and Apple Watch with no additional setup required after activation.
Strong Password Suggestions
iCloud Keychain can generate and suggest strong, unique passwords for your accounts during sign-up.
