Advanced Data Protection is an opt-in feature with a rather serious caveat: if you somehow lose the encryption key (password) to your encrypted iCloud data, Apple wouldn't be able to restore your information. During the setup of Advanced Data Protection, you are prompted to add an alternate recovery method, just in case. On the upside, the new security feature will keep your data safe even in the case of a cloud breach, which has definitely happened to Apple in the past. The feature is currently available in the US only, but will rollout to the rest of the world in early 2023, says Apple.
