A few days ago after testing on beta users, finally the Facebook-owned WhatsApp is now up for the users for fingerprint unlock specifically for all the Android users. This feature is specifically offering biometric security to Android and this feature has rolled out after around 8 months after the similar features rolled out on iPhone. iPhone users were earlier enjoying the benefits of Face ID, also known as facial recognition as well as Touch ID, also known as fingerprint recognition back in February of this year. The Fingerprint Lock security update which has been landed recently is for the WhatsApp version 2.19.222 of the Android WhatsApp app. Not only this but also this feature provides all the Android users with a security option which is more in the queue along what is present in the iOS version of the app. We all known and we have also mentioned above that iPhone users are already enjoying the Face ID as well as Touch ID support. On this WhatsApp mentioned, “today we are introducing similar authentication, allowing you to unlock the app with your fingerprint, on supported Android phones.” Through this, we can understand that fingerprint is the only available option for Android users. WhatsApp has not yet enabled the face unlocking for Android phones and they have also not hinted about it that it will be in the future.  

With the help of this feature, users of Android phones can even choose on how much time the app they want to automatically lock in from immediately after closing to after 1 minute as well as after 30 minutes. Not only this but they also can select whether the messages which appear on the notification bar should be visible to them including the sender of the messages which we feel is great. Back in August, the Facebook-owned messaging app known as WhatsApp has rolled out this feature for bet testing about 8 months after it was earlier spotted as a hidden feature. This is one of the most important as well as much needed features for which the developers are working very hard on behind the scenes. Having said that, at the time of the course of development, the Fingerprint Lock feature has undergone several name revisions. Initially, as per the reports, this particular feature was previously known as Authentication and later on renamed to Screen Lock. Here the developer does not want to confuse the users just for the name and so they have renamed it which best reflects so that it does not create any sorts of confusion. 

If your WhatsApp is not on version 2.19.222 then you have to check for the updates on your Google PlayStore. After ensuring that you are operating the particular version and still you are not able to access the latest feature, then you again need to reinstall the app. Not only this but you also have to take a backup of your chat history at the time or just before uninstalling the app. This particular feature will be offering the users of WhatsApp an extra layer of security for preventing others from reading the messages. You will be able to find this particular feature in the “Privacy section just under the “Account” option which is available in WhatsApp “Settings”. Now if you want to enable it on WhatsApp, you have to go to Settings≥ Account ≥ Privacy ≥ Fingerprint lock. Now here if you are willing to enable the Fingerprint lock of WhatsApp, then it will be asking you for the authentication where your fingerprint will be stored in the OS. Having said that, this particular feature comes in three different options o lock the app automatically. Now the first option is “immediately”. The second option is “After 1 minute”. Last but not least, the third option is “After 30 minutes.” One more point which you have to note that the fingerprint lock feature of WhatsApp does not block the calls but it only hides your messages. Apart from this, the WhatsApp widget also hides the content which most of us find it in the notification panel. WhatsApp decided to take this step soon after it sued Israeli firm NSO Group or spying around 1,400 journalists as well as Activists of India. This group has used the state of the art Pegasus spyware for attacking the users. At that point in time, the company has requested all its users all around the world to update their app to get the new version of WhatsApp. This particular spyware worked on a major vulnerability which is known as “zero-click zero-day”. Through this, the attackers can immediately infect the smartphone. They can even inject the spyware through the WhatsApp video calls. Now finally WhatsApp is here with this new update.
