Facebook has finally given people who use its popular chat app – Facebook Messenger – the chance to secure their talks. All 900 million Facebook Messenger users are now able to opt-in their app with a new feature – “Secret Conversations” which allows to encrypt their conversation, so that no one can read them except the two people on either end of a conversation – not even Facebook or law enforcement or intelligence agencies.
The new feature also allows senders to choose a Snapchat-style expiration time for messages, ranging from 5 seconds to one day.
This feature is available in the new versions only, so be sure to update your app now.
Secret Conversations are based on the Signal encryption system, which was developed by the nonprofit Open Whisper Systems, which first implemented the encryption layer in its own Signal App before partnering with other companies to include the protocol.
Facebook Messenger’s new encryption feature is not default and you should enable it manually for every conversation, that is not so convenient. But it’s strong. In combination with using a VPN app on your device, securing your Wi-Fi connection and ensuring your device’s privacy, million of people can safe their communications.
