Must have iPhone X feature enabled through Face ID

[bpeeps]

You can set the notification setting to show your notifications before you swipe up when it sees your face to unlock them . if it does not see your face, the notifications don't show. So no one can pick up your phone and see your notifications while you are away.

For additional security, Face ID is attention aware, meaning it unlocks your iPhone X only when you look toward the device with your eyes open. That means Face ID can also reveal notifications and messages, keep the screen lit when you’re reading, or lower the volume of an alarm or ringer.

iOS 11 has a new setting to do this for all notifications. can be used with touchID too, but i think faceID is more convenient for this.
