installed version 2.19.221, you should see the Fingerprint lock option in Settings > Privacy, but it may also be linked to a server-side switch, so don’t panic if you don’t get it straight away. You might be able to force it by deleting and reinstalling the app, but make sure you back up your chats if you do!

Once you have the option, it’s fairly straightforward. WhatsApp will talk to your phone and allow your saved biometric credentials to work with the app, then you’ll be asked whether you want it to lock as soon as you close it or wait for 30 seconds/1 minute. There’s also an option that allows you to hide notification content when locked.
