Before you go ahead and try to do the same trick on Facebook web or Messenger web, let us stop you right there. The secret conversation option is only available on Messenger iPhone, Android, and iPad apps.

Recent conversations in Facebook Messenger are separate from normal chats. When you compose a secret conversation in Messenger, the app will create another chat thread with the same person. Your normal chat remains untouched.

Secret conversation identification

You can separate secret conversations from regular chat by checking out the little lock button below the profile picture on the Messenger home screen.

Secret Conversation Content Support

You can think of a secret conversation in Facebook Messenger as a stripped-down (but much more secure) messaging experience.

Secret conversations in Messenger allow you to send the following format.

  • Text messages
  • Pictures
  • Messenger stickers
  • Videos
  • Voice recordings
  • Voice and video calling

However, you can’t start a secret conversation in groups, and can’t send gifs either. The secret conversation doesn’t support payments either.

Quite a lot of limitations if you ask us. If these functions are important to you, you should avoid using secret conversations in Facebook Messenger.

To ensure that the secret conversation is indeed encrypted, you can compare the device key on your phone with the one on your friend’s phone. Here’s how.

Step 1: Open Facebook Messenger and go to any secret conversation.

Step 2: Tap on the info button in the upper right corner.

Compare the keys with your name on your friend’s device using a screenshot. Let’s say, your device keys are 345 on your phone. It should reflect the same under the other person’s phone.

Delete Secret Conversations in Messenger

Once you are done with secret messaging in Facebook Messenger, you should delete the chat. That way, you can avoid those chats from any unauthorized access. Here’s how to delete secret conversations in Facebook Messenger.

Step 1: Launch Facebook Messenger and open a secret conversation.

Step 2: Tap on the info button at the top and open the profile menu.

Remove messenger

Confirm your decision.

Using Multiple Devices with Secret Conversation

You can always use multiple devices to start a secret conversation. If you have another iPhone or Android lying around, you can also use secret conversation on them.

However, don’t expect your previous secret conversations on the last phone to appear here. You will start fresh on a new phone, and Facebook won’t sync secret conversations from your old phone to a new one.

When you start using a new phone, you and the participant will get a notice letting both know you are on a new device.

Enjoy Private Conversations

Unlike Snapchat, there is no way to detect if the other person is taking screenshots from secret conversations in Facebook Messenger. Before sharing confidential media and other information in a conversation, keep this in mind.
