Following is a statement from that guide: "For all Data Protection classes except No Protection, the encrypted data is read from the device and sent to iCloud. The corresponding class keys are protected by iCloud keys." | |

Let's consider a situation where a two-factor-authentication is enabled by a user for his/ her apple account and the iCloud backup is turned on. In this case the backup includes the protection key of the files. And whenever a new device is setup, we only have to provide "passcode" of the current device to access the files. Therefore, I think knowing the passcode, Apple can read all the files. Kindly correct me if I am missing any crucial point. | |
