Enable Fingerprint Lock on WhatsApp for Android Device.
What is Fingerprint Lock?
A fingerprint scanner is a type of electronic security system that uses fingerprints for biometric authentication to grant a user access to information or to approve transactions.
Is Fingerprint Lock Secure:
According to a news on Verge which say’s and I quote:
“In five minutes, a single person faked a fingerprint and broke into my phone. It was simple, a trick the biometrics firm Vkansee has been playing at trade shows for months now. All it took was some dental mold to take a cast, some play-dough to fill it, and then a little trial and error to line up the play-dough on the fingerprint reader. We did it twice with the same print: once on an iPhone 6 and once on a Galaxy S6 Edge. As hacks go, it ranks just a little harder than steaming open a letter.
Of course, this particular method only works if you have help from the person whose fingerprint you need — and even then, it’s not a foolproof system. As luck would have it, my own fingertips turned out to be too smooth to leave an impression, so we had to rely on our director Phil Esposito, who had his thumb successfully molded and used it to unlock both phones.”
Okay Let’s get down to business.
