WhatsApp initially rolled out touch ID and face ID support for iPhone users earlier this year and now fingerprint lock layer of security is now available for Android users. As expected the fingerprint option will only be available if your phone has a fingerprint scanner.

Activating the new Whatsapp fingerprint lock on Android is pretty simple and straightforward. First, make sure you are on the latest version of WhatsApp, laiunch the app, click on the three dots on the top right corner and tap on Settings >> Account >> Privacy >> Fingerprint lock. After that, just turn on Unlock with fingerprint to confirm your fingerprint and you are good to go.
