Facebook Inc rolled out end-to-end encryption for voice and video calls on Messenger. The multinational technology company added another layer of privacy to its widely used communications platform.

Facebook's WhatsApp and Messenger services already have end-to-end encryption on personal texts messages sent by users. And now, the social media giant has gradually been adding audio and video features to its portfolio of messaging services. In a blog post, Facebook said "We`ll also kick off a limited test with adults in certain countries that lets them opt-in to end-to-end encrypted messages and calls for one-on-one conversations on Instagram," adding that the security feature will also be tested in the coming weeks on Messenger`s group chats. Meanwhile, Facebook-owned WhatsApp recently launched the ‘view once’ feature for its millions of users across the world. 

The American company added that “On many phones, simply taking a photo means it will take up space in your camera roll forever. That’s why today we’re rolling out new View Once photos and videos that disappear from the chat after they’ve been opened, giving users, even more, control over their privacy."
