A password and key management service provided by Apple that supports cross-device synchronization of Passkeys, securely syncing private keys among a user's Apple devices via iCloud.
Timeline (last 90 days)
The iCloud Keychain synchronization protocol is based on a circle-of-trust mechanism, where a new device joining must authenticate through an existing trusted device or recovery key
A keychain entry will only be included in iCloud sync if the kSecAttrSynchronizable = kCFBooleanTrue attribute is set; local entries that do not sync by default require separate handling during migration
