This also makes security audits simpler for independent specialists, who have torn apart the code and published findings that everything works as intended. Signal is open source, meaning the code is available for anyone to review. You don’t need to take their word for it. While regular phone calls or text messages allow your phone company to unscramble your conversations, even the team behind Signal can’t listen to them.
