On Friday, the social network announced a limited beta version of Messenger for Android and iOS with an end-to-end encryption E2EE feature dubbed secret conversations.
Secret conversations will only be available to a limited number of users at first, with a wider roll out planned for later this summer.
Messenger s secret conversations won t be like WhatsApp, which offers complete E2EE for all messages when all users in the conversation have a compatible version of the app.
Group messaging will not be covered.
While the message is in transit from one device to the other it won t be possible for third parties—including Facebook—to decipher the message.
