"Earlier this year, we rolled out Touch ID and Face ID for iPhone to provide an extra layer of security for WhatsApp users. Today we're introducing similar authentication, allowing you to unlock the app with your fingerprint, on supported Android phones," WhatsApp further said in its blog post. 

Once the fingerprint is set, you can access chats only by scanning it. However, it will still be possible to reply to messages from the notification shade while the app is locked. Users who use the app frequently can also select an option delay the fingerprint lock. The options available are Immediate, After 1 minute, and After 30 minutes.
