The Facebook Messenger app is now making it easy to encrypt the messages you send. Not this only works on one device at a time and you have to let Facebook know that you want the message to be encrypted. How secure is it? Even Facebook can’t read the message. Of course, that doesn’t stop the person receiving the message from taking a screenshot.
Here’s how it works. Open Messenger and the icon for your profile.
Scroll down and tap Secret Conversation.
Make sure it’s turned on.
Now, it’s super-simple to start an encrypted conversation. Either start a new conversation or open an existing one and hit the i icon at the top right.
Scroll down to Secret conversation and tap.
The other person will be notified that it’s an encrypted conversation.
The message will say it’s encrypted and also display in a different color.
You’ll be able to send messages, pictures, and stickers. But Secret conversations don’t’ work with gifs, videos, voice and video calling, or payments. And you can’t use this with group messages.
