Quote:Facebook is believed to be working on adding facial recognition to the Messenger app, essentially providing users with a new protection layer when they want to prevent unauthorized access to their conversations.
 
An early version of the feature was spotted by developer Jane Manchun Wong in Facebook’s Messenger app, and at first glance, it works just like the biometric locks available in WhatsApp.
 
Users will be allowed to enable facial recognition authentication from a dedicated screen and choose when they want the lock to come into effect, with the available options currently including 1 minute, 15 minutes, or 1 hour after leaving Messenger.
 
“When enabled, you will need to use Face ID to unlock the app. You can still replay [sic] to messages from notifications and answer calls if the app is locked. Your Face ID is not transmitted to or stored by Facebook,” the description of the feature reads.
