WhatsApp's Fingerprint Unlock Feature Arrives On Android Beta v2.19.221

 WhatsApp has finally brought the fingerprint lock feature to Android beta users 6 months after it launched the feature for iOS users.

This old, sorry, new feature is available on WhatsApp beta version 2.19.221 for Android but disabled by default. To enable it, go to Settings > Account > Privacy > Fingerprint lock.

Once enabled, this feature will add an extra layer of protection to users chat in the WhatsApp app. The once of the device will be the only person to access his or her chats. The feature also gives users a 'show content in notifications' option which allow users to decide if they want to show or hide message and sender preview when the fingerprint lock is enabled.

Users will also decide if they want their device to lock as soon as they closes it or wait for  30 seconds or 1 minute. Users will decide for themselves the one that suites them more.

WABetaInfo who first spotted the feature says that Android users should worry about privacy and data related issues since WhatsApp itsef doesn't have access to users fingerprint data. The Android system manages the authentication process for WhatsApp which uses Android official APIs.

"I can say that it;s safe for your privacy to enable the Fingerptin lock feature because WhatsApp, as any other app cannot (have) access to your fingerprint data: the authentication process is amanaged by the Android system: WhatsApp uses official ANdroid APIs, so no information is sent to WatsApp/Facebook Server," WABetainfo said.

WhatsApp most times is very slow in implementing new features. This fingerprint unlock feature was first seen in WhatsApp 2.19.3 beta version for Android in January this year but was disabled at that time. We've gotten to the second half of the year before WhatsApp has decided to enable the feature for testing.

The Dark mode feature which is currently being tested might be released in the fourth quarter of the year...that is, if it eventually gets released.

For now, any Android user can download the WhatsApp beta app directly from Google Play Beta Programme  or from APK Mirror.

If you install the app and you don't see the feature right away. try re-installing again because it might be server based.
