Facebook's new encrypted messaging feature, Secret Conversations, is now live for everyone on Android and iOS.
Secret Conversations allows Messenger users to send end-to-end encrypted messages to their Facebook friends.
Group conversations are not included in Secret Conversations.
How to use Secret Conversations
From the Messenger landing page, tap on your profile section, which is the person icon on the upper right of the screen. Scroll down until you see Secret Conversations and tap it. On the next screen, make sure the Secret Conversations slider is activated. Once it is, Secret Conversations are enabled for your device.
There are two ways to start an encrypted conversation in Messenger. The first is to create a new message as you usually do. Right at the top of the message creation screen you’ll see a lock icon next to a slider button. Click that and the screen theme changes color from blue to black. Now, choose the contact you want to start an encrypted conversation with, and you’re on your way.
After you send an encrypted message the person receiving it will have to agree to use the Secret Conversations feature. Once they do, they’ll see your message.
The second way is to initiate an encrypted conversation from a pre-existing message thread. Tap the i icon in the top right-hand corner of the message thread, and on the next screen tap Secret Conversation. The screen will turn to a black theme again, and you’re good to go.
To view an open secret conversation thread just choose it from the list of open message threads on the main screen of the app.
Secret Conversations work almost like regular Facebook messages but not quite. You can send text, emoji, stickers, and pictures; however, gifs, videos, voice calling, and payments are not supported
