WhatsApp chats already have end-to-end encryption, but what about your online backups? They’ll be covered soon, too. As The Verge notes,, WABetaInfo there is discovered that the latest WhatsApp beta for Android (22.214.171.124) includes a test for end-to-end encrypted backups in the cloud. Opt for it and you don’t have to worry hackers or spies will easily read your conversation history.
There are some caveats. You will need to create a separate password to restore the backups and you cannot restore them if you both lose your phone and forget that password. You can alternately create a 64-digit encryption key, but you also have problems if you lose that key.
It is not certain that WhatsApp will implement secure backups in the cloud with the next stable release, so you may not want to count on it in the near future. It is also unclear whether everyone who uses the new beta gets the same backup.
The timing is at least appropriate. WhatsApp has just started testing synchronization with multiple devices which does not depend on the telephone connection. These encrypted backups don’t seem to be available on all devices, but they could prove reassuring as people become more and more dependent on WhatsApp to chat on all their devices.
