WhatsApp has been working on fingerprint unlock feature for quite some time. After testing it internally, WhatsApp is now making the nifty feature available to the users. The latest version, WhatsApp beta 2.19.221 for Android lets the users to locked down the WhatsApp using their fingerprint.
WhatsApp being the popular medium for exchange of information, both official and unofficial, the fingerprint lock is a much needed facility. In fact, the feature should have been present since a long ago. Well, it’s better to be late than never.
The users on WhatsApp beta channel can make use of the facility and secure their chats. In order to do so, head over to WhatsApp Settings > Account > Privacy > Fingerprint Lock. Enable the toggle and you’re good to go.
It’s pertinent to mention here that the fingerprint unlock is available on devices with Android Marshmallow and above. Obviously, the device should feature fingerprint sensor as well.
Those who’re skeptical about WhatsApp using the fingerprint data, it looks like nothing is to be worried. WhatsApp reportedly makes use of Android’s fingerprint APIs, so your fingerprint data is only used on-device for authentication and not sent to Facebook’s servers. Users concern are obvious as Facebook DNA lies in WhatsApp. You very well know the former has received many backlashes concerned to its approach towards users privacy. Well, we’re not going deep into that matter now.
WhatsApp: Google Play Store.
If you’re a “betaphobic” then wait for the feature to hit stable channel, which we expect to happen soon. We’ll notify once it attains stable release, still then tuned with us.
