WhatsApp is testing a new feature that will allow users to protect the data stored in their chat backups.
Currently, WhatsApp on iPhone allows users to bacck up chats on iCloud, but messages and data are not protected by end-to-end encryption while on the cloud. There new functionality would solve this problem, allowing users to encrypt and password-protect the chat backup before uploading it to iCloud.
This feature is being tested and at the moment we don’t know if and when it will be released for everyone. Meanwhile, you can enjoy the dark mode.
