Enabling Advanced Data Protection and end-to-end encryption in iCloud is a pretty big deal in data protection from Apple. This function is currently not available to the general public, but fans of experiments and beta versions of the software can already test the new protection on their own devices.
One of the functions that received end-to-end encryption is iCloud backups. And here’s what you need to put it into action.
To begin with, you will have to download the beta version of iOS 16.2. Its public release is scheduled for the end of the year in the US, and early next year for everyone else. Next, you need to make sure that all devices added to the iCloud account also have the latest version of the OS (or remove them from the account). And this also applies to all HomePods and Apple TVs.
After that, you can go to Settings -> iCloud -> Advanced Data Protection. To activate the function, you will also need to activate the options for restoring access (Account Recovery). It can be a separate key and a trusted contact. The latter will require confirmation of the action, and it is better not to lose the 28-character key.
After that, you just need to go through several steps that the system will offer to activate encryption. Everything is done.
