Messenger previously had the option to turn on end-to-end encryption, allowing a message to be read only by the sender and its recipients, but with this change messages would be encrypted by default, Meta said.
The end-to-end encrypted conversations also offer additional functionality including the ability to edit messages, higher media quality and disappearing messages.
Facebook has recently shared an update on its plans to switch on end-to-end encryption by default in its Messenger chat platform. The social media giants mentioned that it began testing the feature for chats “between some people” recently.
