Popular encrypted messaging app Signal adds video calls
If you send encrypted text messages from your phone, there's a decent chance you use Signal. Since the app made headlines in 2015 by offering encryption between Android and iPhone, it's grown in popularity, to the point that it's now one of the preferred ways to tip The New York Times on a story.
As of today, Signal will do video calls as well.
Mind you, Signal creator Open Whisper Studios is calling the feature a beta for now, which suggests it might still have its share of bugs. And if you're using an iPhone, there's one thing you may want to do for security's sake as well: since the app uses Apple's CallKit on iOS 10 to let you answer calls from the lock screen, it will send a record of who you called, and how long you spoke, to Apple's iCloud servers.
