Encrypted chat Encrypted Connection Forward Secrecy Group chat Works offline too Protected by Password Based on phone number Self destructing messages Video calling Voice messages Add a feature Signal uses open source, end-to-end encryption to keep your messages to another Signal user secure and private. It installs on your Android and replaces your default messaging app. (On iPhone it's a separate app.) It's super easy to use. You can still send messages to people who don't have it, but I'd encourage everyone to use it. Plain SMS messages are routinely recorded and stored forever without your persmission. Signal combats that in a very user friendly way. JohnFastman • Nov 2016 • 5 agrees and 1 disagrees Disagree Agree Desktop support via Chrome App only. Are you serious?
