Facebook-owned WhatsApp already has end-to-end encryption activated by default on its messaging platform. And it looks like Facebook itself is mulling over the idea of bringing this into its own Messenger app. But unlike WhatsApp, end-to-end encryption will be a separate mode that users need to enable. The Guardian reports the opt-in approach is being taken with Messenger because having messages encrypted means Facebook will interfere Facebook’s machine learning, which is needed for its recently launched chat bots.
