Facebook says it has worked with engineers, cryptologists, designers, and policy experts to bring end-to-end encryption to Messenger and make chats private, safe, and secure. End-to-end encryption is still in its testing phase, and this rollout will be part of that testing.
"Building a secure and resilient end-to-end encrypted service for the billions of messages that are sent on Messenger every day requires careful testing," said Meta.
As of Monday, these end-to-end encrypted chats will have new features previously exclusive to regular Messenger chats. Encrypted chats will now have chat themes, custom chat emojis, and reactions, group profile photos, link previews, and active status.
Android users get an added bonus -- bubbles. Bubbles on Android is a feature that shows you a circle with your friend's photo, also known as a bubble, while using other apps that you can use to read and reply to messages.
