There are many reasons why WhatsApp is so popular, but one of the most important is the service's focus on user privacy. With end-to-end encrypted messages, users of the app can be sure that their messages will arrive directly at the recipient without the risk of someone looking at them on the way.
Now Facebook has announced its plans to take privacy even further. The next logical step is to extend end-to-end encryption to WhatsApp backups as well.
It has been known for a long time that it is being worked on, but now it seems to be on the home stretch. It took a little longer as there were major technical challenges. You had to create a new framework for key and cloud storage.
If you have set up end-to-end encryption, either by securing your key manually or with a user password, neither WhatsApp nor Facebook have access to your saved chats.
There is still no date when WhatsApp will roll out the new security feature. But it is expected in the next few weeks.
