WhatsApp supports end-to-end encryption for its messages. What this means, for those unfamiliar, is that the messages are encrypted while in transmission meaning that even if a hacker were to intercept it, they wouldn’t be able to read it as it can only be decrypted on the intended device.
However, when it comes to backups, that’s a slightly different story. However, the good news for those who might be worried about their WhatsApp backups is that it now seems that the company could be working on introducing end-to-end encryption for its backups as well. This will involve users choosing their own password for when they want to restore their backup.
Alternatively, WhatsAApp also seems to be offering users the ability to create an encryption key. This will consist of 64 alphanumeric characters which would be a lot stronger and harder to guess, but WhatsApp does state that should you lose this encryption key, there’s nothing that they can do about it.
There is no word on when this feature will be rolled out, but it sounds like a good idea to have anyway, especially with the company on the cusp of launching support for multi-device, so having a more secure way of backing up your chat data from multiple sources sounds like a good feature to have.
