Facebook Messenger Starts Testing End-to-End Encryption
Starting a secret conversation with someone is optional. That’s because many people want Messenger to work when you switch between devices, such as a tablet, desktop computer or phone. Secret conversations can only be read on one device and we recognize that experience may not be right for everyone. It’s also important to note that in secret conversations we don’t currently support rich content like GIFs and videos, making payments, or other popular Messenger features.
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.
