Meta finally announced that Facebook and Messenger will have default end-to-end encryption for private messages and calls.
End-to-end encryption will safeguard users’ chats, so all information within the chats is protected from potential interception or access by third parties, including service providers or hackers. Only the user and their chatmate can see the content. The chats will only be visible to the company if a user reports a message to them.
Meta has built their end-to-end encryption on cryptographic principles using the Signal Protocol and its own Labyrinth Protocol.
The apps will automatically enable the feature once updated. However, a global roll-out may take several months to complete.
Users will know the feature is up once Messenger asks them to set up a PIN as a recovery method to restore messages in case of device loss or change.
Additionally, End-to-end encrypted conversations on Messenger now offer disappearing messages that last up to 24 hours, with notifications for when someone takes a screenshot.
