The facebook-owned app, WhatsApp started rolling out the long-awaited feature for its iOS beta users. The new feature enables WhatsApp to automatically backup users’ encrypted chat history on iCloud and you can also protect them with a password. WhatsApp was in the works to release the feature for a long time and finally, they released it on WhatsApp beta for iOS.
The users can secure their chat by backing it up to restrict unauthorized access by any means. Once your backup is end-to-end encrypted, no one except you can access the backup. The backup is end-to-end encrypted and those including WhatsApp, Facebook, and Apple only cannot see its content, because it’s encrypted using a password or a 64-digit encryption key.
According to WhatsApp, the backup key Vault has a strong power blocking mechanism that makes it impossible to permanently access the key after a limited number of failed recovery attempts. By visiting WhatsApp Settings > Chats > Chat Backup > End-to-end Encrypted Backup, you can check whether the feature is available on your device or not if you are a beta user.
Moreover, WABetaInfo says that you should disable WhatsApp from your regular device backup that lacks end-to-end encryption when you enable this feature. You can do that from Settings -> Your Name -> iCloud -> Manage Storage -> Backup -> Disable WhatsApp. After enabling end-to-end chat backups when you switch phones, you will need to manually restore the chat history from WhatsApp.
