Facebook has introduced new end-to-end encryption (E2EE) for voice and video calls on its Messenger platform to enhance privacy and security.
The new feature will not be activated by default as users can manually opt for the feature before calling a person. According to Facebook, the feature will send messages or calls in an encrypted form which can only be decrypted by the sender and the receiver, and that "nobody else, including Facebook, can see or listen to what’s sent or said".
In addition, Facebook will be testing end-to-end encryption for group chats and calls "for friends and family that already have an existing chat thread or are already connected". During the test, the feature will only be available to a selected number of users. The company also revealed that a limited test of the same feature will be kicked off for Instagram users.
Alongside the end-to-end encryption update, Facebook has also updated the "Disappearing Messages" feature. The new update will users to choose how long a message will disappear after it is viewed, from 5 seconds to 24 hours.
