WhatsApp's'fingerprint authentication feature ready for launch here's how to activate

One of WhatsApp's most awaited features, fingerprint authentication, is finally rolling out to Android users.

WhatsApp Beta for Android is now receiving a new update with version number- 2.19.3. The authentication is required only when you open WhatsApp. The feature will work on Android Marshmallow and above. If you disable the "Show content in notifications" option, WhatsApp will no longer show the sender and message preview when you have Fingerprint lock feature enabled. Fingerprint lock will also allow users to choose when they must authenticate to use the app, but they can also choose when exactly WhatsApp will automatically lock after use: immediately, after 1 minute, after 30 minutes.

After enabling the Screen Lock feature for iOS beta users, WhatsApp has released the feature for its Android users.

Despite its enormous user base, WhatsApp can often be slow to introduce the most hotly-anticipated new features.

For the United States market, the models will come nicely equipped with the Sport Chrono Package and ceramic composite brakes. With 670 hp and 663 ft lbs of torque apiece, the Turbo S E-Hybrid and Turbo S E-Hybrid Coupe lead the 2020 Cayenne range.

By making it to the public beta, all WhatsApp users on the Android platform can expect the same feature to show up on their devices in the coming weeks once WhatsApp is done with its testing. You might be able to force it by deleting and reinstalling the app, but make sure you back up your chats if you do!

In simple words, if you unlock the app via fingerprint every time you need to reply to a message, then that can be annoying for some. So if you choose anything but "immediately", you get a specific amount of time from your last use of WhatsApp during which the app stays "unlocked" and won't require a fingerprint again.

WABetaInfo spotted this feature first, and says, "I can say that it's safe for your privacy to enable the Fingerprint lock feature because WhatsApp, as any other app, cannot access to your fingerprint data: the authentication process is managed by the Android system: WhatsApp uses official Android APIs, so no information is sent to WhatsApp/Facebook Server".
