WhatsApp message are already securely encrypted as they are passed between the people who are sending them, meaning that nobody – including WhatsApp – is able to see them. But, until now, any backups of those messages have not been encrypted, leaving them potentially open to hackers. WhatsApp has launched a major new security update, meaning that it is fully embracing end-to-end encryption. That level of security does, however, come with a cost. If a user loses access to their backups, there will be no way to get them back. Is this a threat to the user since you cannot get the backup once you have lost it ?
