It has been coming for quite some time, but Facebook is now finally rolling out end-to-end encryption on some parts of Facebook Messenger.
Facebook is begining with end-to-end encryption for voice and video calls, which is starting to roll out to users now. This is something Whatsapp (another Facebook service) has had for a long time. However, unlike Whatsapp, end-to-end encryption on Messenger is so far only reaching calls: there appears to be no news on getting the encryption on messages. Despite this, Facebook are testing end-to-end encryption for group chats, including voice and video calls.
Instagram is beginning a limited test with opt-in end-to-end encryption, which does appear to be for messages, although it is unclear if this includes images sent across Instagram to a single user. Facebook have not yet said when this will rollout to all users on Instagram, but it is possible that it may be quite some time before it does.
All these changes from Facebook are very welcome, security and privacy is something which many people are becoming more aware of recently, with many users opting for more private platforms such as Signal. It is important for Facebook to keep up and offer users the option for total privacy and that is exactly what end-to-end encryption offers – whatever you send is only visible to the person you send it to. It would certainly appear end-to-end encryption is now very mainstream and Facebook does not want to miss out.
