WhatsApp to launch a new fingerprint lock feature

A Dark mode is still in the works, but fingerprint unlocking already came to iOS a few months ago. Screen lock is available for users on the abovementioned Beta release, and who are using it on Android Marshmallow and above.

Facebook-owned messaging app WhatsApp has today rolled out a feature where you will be able to unlock WhatsApp on your smartphone by using the fingerprint sensor on your Android device.

There's a 15 minute option on the iOS app, but that hasn't trickled down to the Android version, and hopefully the company will introduce it when the feature is rolled out in the stable version. It is disabled by default, which means users will have to enable it manually by going into the app's settings menu. Spies and philanderers alike rejoice with the news that you will finally be able to keep your instant messages safe from prying eyes.

However, once enabled, the fingerprint security will require you to produce your fingerprint whenever you attempt to open the application.

If you are not on the latest version of beta app, which is 2.19.221 then you need to update the same by heading to Google's Play Store. You might be able to force it by deleting and reinstalling the app, but make sure you back up your chats if you do!

Fingerprint authentication has been around on the platform since past year to iOS users.

WhatsApp has announced a new Fingerprint lock feature that was previously called Authentication or Screen Lock feature according to WABeta Info. However, the reports confirm that the users will be able to reply from the notification or receive calls once the lock is activated. WhatsApp has also added an option to hide message content in notifications preview if the fingerprint unlock is enabled. The time span options to lock the WhatsApp includes - after a minute or 30 minutes or "Immediately" to lock the app instantly. WhatsApp is also rolling this feature as a server-side update.
