Messages included in the “secret conversation” are end-to-end encrypted, and therefore the conversation can only be followed on a single device. This is same as Whatsapp end-to-end encryption.

“It is really hard to get an encrypted messaging app that has all the features that Facebook wants to work on the web and on multiple devices”, Green noted.
Meanwhile, Matthew Green, an assistant professor of computer science at Johns Hopkins University, who was invited by Facebook to review its end-to-end encryption effort, said he would like to see the feature turned on by default but agreed that this would be a challenge.
Furthermore, users will be able to report any abuse but Facebook will not be able to read reported conversations before a certain delay. Only the owners of the devices sending or receiving the message can view them. There are further restrictions.
Facebook Holds Back An End-To-End Encryptions For Messenger:Facebook has started testing a new feature for Messenger that will allow users to create one-to-one conversations with end-to-end encryption. Users can choose covert communication set a timer to control how long each message remains visible.
The service is built on the Signal Protocol by Open Whisper Systems, one of the most trusted cryptography technologies.
Facebook Inc. on Friday said it is beginning to roll out an encrypting option on its Messenger app in a bid to offer a more confidential way of communicating on its messaging system. The intention is to make the encryption feature available for all users, and platforms of Facebook Messenger.

End to end encryption was automatically enabled for all WhatsApp users from April 2016 but in May we were told that a similar feature would be brought to Facebook messenger. It will also help in transforming the sidebar conversation nature of Messenger to a more private conversation platform, believes the company.
