WhatsApp has finally begin to introduce the fingerprint unlock feature on Android smartphones, something that has only been on the iOS platform for some time now.
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.
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.
Any WhatsApp user can decide to set the time limit before your WhatsApp gets locked. You can decide to set it to lock immediately after you quit the WhatsApp messenger or 30 seconds after or a minute after. It all depends on you.
