Facebook Messenger : End-to-end encryption and secret conversations
Facebook is rolling out a new option within Messenger to better support conversations about sensitive topics.
Facebook Messenger to launch Secret Conversation
In order to better support conversations about sensitive topics, Facebook is now rolling au brand new option in Messenger. Because there are times when people want additional safeguards — perhaps when discussing private information like an illness or a health issue with trusted friends and family, or sending financial information to an accountant, Facebook is starting to test the ability to create one-to-one secret conversations in Messenger that will be end-to-end encrypted and which can only be read on one device of the person the user is communicating with.
A new option that means that the messages are intended just for the user and the other person — not anyone else, including Facebook. Within a secret conversation, user can also choose to set a timer to control the length of time each message remains visible within the conversation. Facebook’s technology uses the Signal Protocol developed by Open Whisper Systems.
Starting a secret conversation with someone is optional. According to Facebook : “that’s because many people want Messenger to work when you switch between devices, such as a tablet, desktop computer or phone”. Secret conversations can only be read on one device, Facebook annouces that secret conversations don’t currently support rich content like GIFs and videos, making payments, or other popular Messenger features. Secret conversations are currently available on a limited test basis, but Facebook will be making the option more widely available this summer.
