During the course of development, the Fingerprint Lock feature has undergone a number of name revisions. As previously reported, the feature was initially known as Authentication and later renamed to Screen Lock. WhatsApp wants to ensure that the name of the feature best reflects what it does while not creating any confusion. According to a report by WABetaInfo, this feature is now available Android beta users running the app version 2.19.221. If you are WhatsApp beta user then you can double-check the version by going to App info under the Help menu in the Settings section.

If your WhatsApp is not on version 2.19.221 then you need to check for updates on Play Store. After ensuring that you are running the required version, if you still can t access then feature then you should reinstall the app. Make sure that you take a backup of your chat history before uninstalling the app. Now that you have the required version, the feature is in the Privacy section under Account option in WhatsApp Settings .
If you enable the Fingerprint Lock feature then it will ask you to authenticate your fingerprint stored in the OS. The report confirmed that users can still reply to messages from notifications or receive calls after the lock. This is because the feature only works to lock the main app. The feature comes with three options to Automatically lock the app. The first is immediately , the second is After 1 minute , and the third is After 30 minutes . The feature also allows users to enable or disable message context preview in the New Message notifications. WhatsApp widget also hides its content when users enable this feature. The report also confirmed that WhatsApp does not have access to your fingerprint data for authentication.
