WhatsApp has been working on this feature for a while.

A new feature Fingerprint Authentication has been spotted on WhatsApp's Android beta update version 2.19.83, enabling users to lock and unlock the app using fingerprint sensor. 
Facebook-owned WhatsApp has been working introduce this feature since a while and the latest update reveals some new features, according to reports in Ndtv.com. Beta tracker WABetaInfo shared screenshots that show the Authentication feature can be enabled in Settings.
However, this feature currently is disabled by default and it not yet clear when WhatsApp will roll it out for the stable version users. When the feature is enabled by WhatsApp it will be found in Settings >Account >Privacy > Use Fingerprint to Unlock. 
Once it has been enabled, WhatsApp will register the user's fingerprint and then prompt user to select an option whether the app should be locked immediately after they leave or after a gap of one minute or 10 or 30 minutes. It will show a sign indicating users to unlock the app using fingerprint authentication. If a user has tried to unlock the app multiple times, an error will pop up. 
iPhone users already have the feature in the stable version of the iOS app, and apart from fingerprint authentication via Touch ID, facial recognition via Face ID is also available to them.
