WhatsApp's fingerprint unlock feature arrives on Android in latest beta

To enable this feature in your app, you need to so to the WhatsApp Settings Account Privacy Fingerprint lock. The latest beta has also bumped the app to v2.19.221.

WABetaInfo, one of the go-to sites for upcoming WhatsApp features, is reporting that there's a new security feature on the horizon for the world's favourite messaging application (outside of China). For the unaware, Fingerprint Lock feature allows WhatsApp users to secure their app via the fingerprint sensor and this feature is pretty much similar to the authentication feature rolled out to iOS users a few months ago.

This new feature will help users in adding a layer of protection to their chats.

WhatsApp announced a brand new fingerprint feature to unlock the app for Android users.

You can choose to hide content in notifications too, once fingerprint unlock is enabled. In iOS, users will be able to secure their app through Touch ID or Face ID (on the latest iPhones), but in Android, it now allows users to secure the app only via fingerprint scanner. Choosing the' immediately' option will require the user to fingerprint authenticate every time they close and open the app.


WhatsApp has rolled out a beta programme for Android users a couple of years ago. It will automatically block content if you have the widget on your home screen.

The new Fingerprint Lock feature on WhatsApp is offered with three options - "immediately", "After 1 minute" and "After 30 minutes".

Once you enable fingerprint unlocking, you'll be able to change the unlock interval.

If you disable this option, you would be able to reply to messages from the notification bar and even accept or decline WhatsApp calls without having to punch in your biometrics. Well, the wait is over, as the feature is finally here on the latest WhatsApp beta app. WhatsApp is also reportedly making use of Android's fingerprint APIs, so your fingerprint data is only used on-device for authentication and not sent to Facebook's servers.
