Facebook Introduces new feature for Messenger - Vanish Mode

Facebook introduces vanish mode on Messenger, which lets you send messages that disappear automatically.

To turn it on, swipe up on your mobile device in an existing chat thread and you’re in vanish mode. Swipe up again and you’re back to your regular chat. 

Only people you’re connected to can use vanish mode with you in a chat. Vanish mode is also opt-in, so you choose whether to enter vanish mode with someone. If someone takes a screenshot of your chat while you’re using vanish mode, you’ll be notified. And as always, you can block someone and report a conversation if you feel unsafe.

Vanish mode is now available on Messenger in the US and a handful of other countries, and it’s coming soon to more places. Vanish mode on Instagram will be coming to the US and other countries soon, when you update to the new Messenger experience.
