End-to-end encryption has become paramount as a hallmark of security on third-party communication channels.

WhatsApp, which is owned by Facebook, prides itself on its state-of-the-art encryption. Now a bigger chunk of the communication conglomerate follows suit as Facebook Messenger has introduced end-to-end encrypted video with voice calls rolling out soon. Not long after, Instagram would also be set to have similar features.

“In the past year, we’ve seen a surge in the use of audio and video calling with more than 150 million video calls a day on Messenger. Now we’re introducing calling to this chat mode (end-to-end encrypted) so you can secure your audio and video calls with this same technology if you choose,” Facebook said in a blog post.

End-to-end encryption gets its importance as a service itself cannot access the contents of messages and calls that come under it, neither can other parties. In simple words, nobody else, including Facebook, can see or listen to what is sent or said.

However, one still has the option to report a piece of communication that falls under this encryption to the service.

Facebook said it will begin testing end-to-end encryption for group chats, including voice and video calls, for friends and family that already have an existing chat thread or are already connected.

Facebook has also updated the expiring message feature within its end-to-end encrypted chats.

“People don’t always want or need their messages to stick around and the timer controls let someone decide when their messages expire in the chat,” it said.

Facebook has now updated this setting to provide more options for people in the chat to choose the amount of time before all new messages disappear. The options range from as few as 5 seconds to as long as 24 hours.

Facebook will 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. However, one will need to have an existing chat or be following each other to start an end-to-end encrypted DM.
