How to Enable Apple’s iCloud End-to-End Encryption at Heart of UK Privacy Fight

Apple Inc.’s feature to enable end-to-end encryption for user iCloud accounts has come under fire in the UK, where government officials want the company to disable it and build a backdoor that lets them access data.

The mechanism, called Advanced Data Protection, upgrades the standard security used for most iCloud features to end-to-end encryption, a system that makes it more difficult for a user’s data to be accessed by governments or hackers. With the feature, things like iCloud data backups, photos, notes, reminders, files and text messages receive that more powerful protection.
