If you forget your password or device passcode， iCloud Data Recovery Service can help you decrypt your data so you can regain access to your photos， notes， documents， device backups and more. Data types that are protected by end-to-end encryption – such as your Keychain， Messages， Screen Time and Health data – are not accessible via iCloud Data Recovery Service. Your device passcodes， known only by you， are required in order to decrypt and access them. Only you can access this information， and only on devices where you’re signed in to iCloud.
