"Facebook Messenger wants to be your primary messaging app. As people become more and more concerned about security, being the best messaging app means being the most secure. That’s why Facebook is finally adding an option for users to encrypt their chats in Messenger.
Messenger will begin to offer an end-to-end encryption feature to a limited test group of users today. It’s a security option that’s been a long time coming for Facebook, which has considered making end-to-end encryption available for several months. The so-called “secret conversations” debuted today will be only visible to the sender and the reader, which means Facebook can’t enable some of the chatbot and payment features that are normally a part of the Messenger experience. However, end-to-end encryption boxes out law enforcement and even Facebook itself from reading users’ chats, ensuring that their conversations remain private.
Messenger has also taken steps to make sure that chats remain secure, even if a user’s device gets lost or stolen. In secret conversations, Messenger will allow users to set an expiration date for a message so that it won’t be visible in the conversation forever. Once the time runs out, the message will vanish from the devices of all users in the conversation. Facebook released technical details about its implementation of secret conversations in a white paper (PDF).
Secret conversation mode will only be available on iOS and Android, not in Messenger.com, Facebook chat, or the desktop Messenger app — at least for now. Facebook’s vice president of messaging products David Marcus told TechCrunch that the addition of end-to-end encryption is intended to help Messenger become everyone’s go-to app."
