Facebook testing Face ID and Touch ID authentication for Messenger on iOSUsers would have to ID themselves even after unlocking their phones...
What you need to know
Facebook is testing improved security on iOS.
It's looking to add support for Touch ID and Face ID to Messenger.
Users would need to unlock their Messenger app separately from their phones.
Facebook is reportedly testing the use of Face ID and Touch ID as a means to make its iOS Messenger App more secure.
According to Engadget:
Facebook is testing a new feature for Messenger that allows users to better protect their messages from prying eyes. When enabled, users will need to authenticate their identity using Face ID, Touch ID, or their passcode before they can view their inbox, even if their phone is already unlocked. (The feature relies on your device's security settings, so however you unlock your phone normally is how you'll unlock the Messenger app.) You can also set a designated period of time after leaving the app for when you'll need to re-authenticate.
