Messenger Starts Testing End-to-End Encryption with Secret Conversations | Facebook Newsroom

Secret conversations are available on a limited test basis right now, but we will be making the option more widely available this summer. During this test, we will gather feedback about the functionality, measure performance and introduce tools to enable you to report objectionable content to us. We are putting a lot of thought into the design and implementation of this feature, and we are grateful to the security and privacy experts who have given us their valuable input.
