Today, Mark Zuckerberg announced the addition of some of your favourite Messenger features to end-to-end encrypted chats, including:
We’ve also begun gradually expanding testing of Messenger’s default end-to-end encryption. We understand that people want a place to connect and that they want to know that their conversations will be private, safe, and secure. That is why we have worked hard to assemble a team of talented engineers, cryptologists, designers, and policy experts who are all committed to implementing default end-to-end encryption on Messenger.
More people will gradually see some of their chats upgraded with an extra layer of protection provided by end-to-end encryption over the next few months. As these individual chat threads are upgraded, we will notify everyone in them. We understand that people will have questions about how we choose and upgrade individual threads, so we wanted to make it clear that this is a completely random process. It is intended to be random in order to have no negative impact on our infrastructure or people’s chat experience. This also ensures that our new end-to-end encrypted threads continue to provide people with a fast, reliable, and rich Messenger experience.
Developing a secure and resilient end-to-end encrypted service for the billions of messages sent on Messenger every day necessitates extensive testing. We will provide updates as we make progress toward this goal throughout 2023.
