Facebook's one-on-one encrypted messaging feature, called Secret Conversations, is now live for all Android and iOS users.
The company says the texts are encrypted on the devices that they're sent from and received.
This means if you're chatting in secret mode on your smartphone, you won't see previous messages on your desktop.
Messages will disappear after a set time, according to a Wired report.
Have you guys seen that 'secret message' feature on Facebook where they're encrypted and notifications look like this? pic.twitter.com/uifvlMOyAd— Me, Stacy (@SilverStGroud) October 4, 2016
For now, Secret Messages is only available on smartphone devices -- here's how it looks.
How to use Secret Conversations
Tap on the "New Conversation" icon at the top right and then hit the word "secret."
Then, choose the contact you want to start an encrypted conversation with, and let the private conversation begin.
A win for privacy enthusiasts, but a loss for relationships
Facebook says it won't have access to the texts -- not even the government. The encryption is an end-to-end type that scrambles the information when it's sent, and only you and the person you message can see the unscrambled note.
This is good news for privacy enthusiasts, but not everyone is excited about Messenger's Secret Messages.
Critics of the new feature suspect the secret messages will do more harm than good.

No animated GIFs, no video, no payments
The encryption is accomplished using the Signal protocol, the same tech used in Google's Allo and Whatsapp, which is also owned by Facebook.
One buzzkill: Secret Conversation users won't be able to send animated GIFs, share videos transfer money.
Facebook rolled out Secret Conversations back in July, but made it available for all Messenger users earlier this week.
