Facebook has begun rolling out end-to-end encryption for its Messenger app. The feature, dubbed “Secret Conversations,” will allow Messenger users to send and receive messages in a way that no one, including the FBI with a warrant, hackers and not even Facebook itself, can intercept them. This new feature will currently be available only to a small number of users for testing. Rest of the Messenger users will get Secret Conversations feature later this summer or early fall, the company wrote in a Facebook newsroom post.
