Facebook is testing encryption as a way to make Messenger more secure—and to entice wary non-users to the app.
The social media giant is banking on users’ increasing desire to privatize their conversations so they’re only available on the mobile devices to and from which they are sent.
This capability is already available on Facebook-owned WhatsApp.
The new function—the ominously named “secret conversations”—lets users set a date for the message to expire. At that time, it will no longer be available on either device.
This is all an effort to become “your preferred and primary communication platform,” Messenger chief David Marcus told The New York Times.
