Meta announced the addition of more features for end-to-end encrypted chats through the Messenger service that we already know and use in plain, unencrypted chats.
These features include chat themes, custom emojis and reactions, group profile pictures, link previews, user status changes, nicknames and chat bubbles for Android devices.
In addition to the above, the company announced that more and more users will see their simple Messenger conversations protected with end-to-end encryption. This will happen gradually and not for all of a user's conversations, as Meta tests to check that everything is working correctly. That is why, after all, it will inform the user about each conversation separately.
Conversations protected by end-to-end encryption in Messenger are stored exclusively on the user's device, the messages do not pass through any Meta server and no one can access them, not even the company itself.
