Facebook is adding end-to-end encryption for voice and video calls in Messenger. The company announced in a blog post that it’s rolling out the change August 13 alongside new controls for its disappearing messages. Some users may also see new test features related to encryption.

Facebook Messenger got end-to-end encryption for text messages in 2016, when Facebook added a “secret conversation” option to its app. Now, that mode also supports calling. Facebook says it’s adding the feature as interest in voice and video calls grows.

According to records, Messenger has more than 150 million video calls per day and Facebook said E2EE function has become “a standard for the messaging service industry”. Currently, other video calling apps such as Zoom, Signal and Apple Face Time are also using this E2EE function.
