  1. According to Gadgets.ndtv, before you continue, ensure the WhatsApp version 2.19.221 or above has been installed.
  2. Launch WhatsApp > and click 3 dots icon on the top-right and head to Settings.
  3. Head to Account > Privacy > Fingerprint Lock.
  4. On the next screen, activate “Unlock with Fingerprint.”
  5. On top of that, you can also set the duration after which it will be possible to use your fingerprint to unlock WhatsApp. Set it to “Immediately”, “After a minute” or “After 30 minutes.”
