Even text messages from phone to phone might not be 100% locked down. The old dictum still holds true, however: If you really want to keep something secret, don’t communicate online at all. I don’t think that it’s necessary to go radio silent on the Internet (obviously!) but having some awareness of what should be discussed in public, open to search engines etc, and what deserves more privacy is pretty darn important nowadays. They’re scanning everything, all the time, and it’s up to us to opt out of those behaviors and actions. Otherwise, you’ll see an red error notice.Given the weird way in which talking about a topic in person or chatting with someone in email or on a social media site seems to suddenly cause ads for that item to surface online, I have stopped being quite so trusting of the tech industry and now agree with you. Sending an encrypted message requires the other person to have opted into the Secret Conversations feature (i.e., have Messenger installed on a compatible device). Click that and the screen theme changes color from black and purple chat bubbles to black and gray chat bubbles. In the upper right of the messaging screen, you’ll see a lock icon next to a slider button. The first is to create a new message as you usually do. There are two ways to start an encrypted conversation in Messenger. For our example, we’re using Messenger for iOS but Messenger on Android works similarly. Now that we’ve got the preamble out of the way, here’s how to use Secret Conversations. The popular messaging platform automatically encrypts messages for all users if they have an encryption-compatible version of WhatsApp on their phone.

That approach is very unlike what Facebook-owned WhatsApp is doing.
