Messenger For iOS: Facebook is testing Face ID.

Facebook is testing Face ID or Touch ID authentication for iOS Messenger users. This feature may be rolled out to all users in the future.

Users of Facebook Messenger Owners of an iOS device may soon have the ability to add a new level of security to their conversations; on the platform, thanks to the integration, now being tested by Facebook, with Touch ID is Face ID, Apple's authentication systems, respectively, via the users' fingerprint or face.

Today, anyone with access to our smartphone can easily open the Facebook Messenger app and read our conversations, as is the case with most iOS applications. Facebook's idea, however, is to allow users to use Touch ID or Face ID to Unblock access to Facebook Messenger, and therefore to our conversations, thus adding an additional layer of protection.

There are already many iOS applications that take advantage of Apple's authentication system, from Amazon to Google Drive, passing through Netflix, PayPal and the apps of various banks and Poste Italiane, but it's unusual for an instant messaging app to do so. It's true, however, that Messenger is increasingly popular, and many users use it as their primary way to stay in touch virtually with friends and family, so the private and confidential information exchanged on the platform is significant.

Hence the idea of making the app a little more secure, to ensure maximum privacy. You can choose to enable Touch ID or Face ID authentication as soon as you close the Messenger app, or after one minute, 15 minutes, or an hour.

Facebook specifies that after an initial testing phase, the idea is to extend the functionality to all iOS users and, in the future, to do the same with Android.
