KSecAttrAccessibleWhenPasscodeSetThisDeviceOnlyĪpps that use background refresh services can use kSecAttrAccessibleAfterFirstUnlock for keychain items that need to be accessed during background updates. NSFileProtectionCompleteUntilFirstUserAuthentication These classes have behaviors equivalent to file Data Protection classes but use distinct keys and functions. Keychain data is protected using a class structure similar to the one used in file Data Protection.

The prefix requirement and application group uniqueness are enforced through code signing, provisioning profiles, and the Apple Developer Program. To share keychain items, third-party apps to use access groups with a prefix allocated to them through the Apple Developer Program in their application groups. Keychain items can be shared only between apps from the same developer. Rather than limiting access to a single process, access groups allow keychain items to be shared between apps. Keychain Access APIs result in calls to the daemon, which queries the app’s “Keychain-access-groups,” “application-identifier,” and “application-group” entitlements. There is only one database, and the securityd daemon determines which keychain items each process or app can access. The keychain is implemented as a SQLite database, stored on the file system. The secret key always requires a round trip through the Secure Enclave. The metadata key is protected by the Secure Enclave but is cached in the Application Processor to allow fast queries of the keychain. Keychain metadata (all attributes other than kSecValue) is encrypted with the metadata key to speed searches, and the secret value (kSecValueData) is encrypted with the secret key. Keychain items are encrypted using two different AES-256-GCM keys: a table key (metadata) and a per-row key (secret key).
