Facebook Messenger will roll out an end-to-end encrypted chat mode in the next few months. Users will be able to send and receive messages that can not be read or intercepted by law enforcement or even the social network itself. The mode would protect your communication between devices from the prying eyes of hackers as well as law enforcement agencies. The update will offer users a choice between privacy and smart AI features, like the ‘Bots on Messenger’ feature that Facebook revealed last month, allowing companies to deliver automated customer support to users.
