The end-to-end encryption offered in WhatsApp messages will also be adopted for in-app backups. The launch will be launched in the coming weeks as an optional feature for iOS and Android users.
The announcement was made this Friday (10) by Mark Zuckerberg, CEO of Facebook, owner of WhatsApp.
With the change, the application will have another layer of privacy. Thus, in addition to the sending, transit and receiving steps, additional protection will also involve backups saved to the device and cloud storage services, such as Google Drive and iCloud.
The end-to-end encrypted backup will be accessible only to the user who created it.. Nobody, not even WhatsApp, will be able to view the content.
The app, which has more than 2 billion users, claims that no other service of its scale provides this level of security for users’ messages.
