Facebook started testing end-to-end encryption (E2EE) for voice, and video calls on Messenger in late 2019, although it did not confirm at the time as to when it would publicly introduce the feature. Now, that chat mode is rolling out to more users.
The release means that anyone but you and the receiver won’t be able to eavesdrop on your calls made through Messenger. Facebook has rolled out E2EE amid growing interest in voice and video calls, with more than 150 million calls on Messenger taking place every day over the past 12 months. It also comes as governments worldwide have been calling on Facebook to push back its efforts to bring the security feature to everyone over child safety issues.
E2EE has also been available for one-on-one text chats on one of the best messaging apps for Android since 2016. In addition to those types of conversations, Facebook is also planning on testing end-to-end encryption for group chats and calls in Messenger and Instagram Direct Messages. The test will be open to a limited number of users on both platforms if they “already have an existing chat thread or are already connected”. On Instagram, however, the experiment will be optional.
