At the end of October, WhatsApp rolled out a security update for its community that allows users to use fingerprint lock in the Android application.
Although the feature is just new for the Android users, the iPhone users already had a taste of the Whatsapp fingerprint lock. Never the less, it’s nowhere on Android so let’s embrace it.
Most of the new smartphones now have biometric technology which includes physical fingerprint scanners to allow users to unlock their devices with fingerprints and high-quality cameras to allow Face ID unlock.
The fingerprint lock is a great addition to the existing privacy and security in the application. So there won’t be any more need for downloading third-party applications to manage the protection of WhatsApp as it has been before.
