Part 1: How to Lock Your WhatsApp with Fingerprint on Android Phones
If you want to keep your WhatsApp account and conversations private, knowing how to lock your WhatsApp with a fingerprint adds an extra layer of security and privacy.
Unlike password lock, where anyone who knows your password can access your chats on WhatsApp, fingerprint lock prevents unwanted access and ensures that only you can open your chats.
If you want to learn how to lock WhatsApp using fingerprint, here is how I enabled WhatsApp fingerprint lock on my Samsung Android phone:
- Open WhatsApp on your Android phone. Then tap on the Ellipsis icon (the three-dot symbol) in the top-right corner of your screen and select Settings.

- Tap on Privacy and scroll down to select App Lock.

- Tap on the Unlock with Biometric toggle switch. Then, confirm your biometric lock by scanning your fingerprint using the device’s fingerprint scanner.

- Next, choose how long you want WhatsApp to stay open before the biometric lock kicks in. You can select WhatsApp to lock immediately, after 1 minute, or after 30 minutes.

- Choose if you want to see content in notifications. Enabling this feature means you can preview the texts inside new message notifications before opening WhatsApp.


Aside from setting a fingerprint lock, WhatsApp privacy settings also allow users to hide their online and last-seen status so no one can know if they are online. While this improves privacy, it also makes it difficult to know when your favorite contacts are online and when to contact them.
What if you could track the online status of any contact on WhatsApp without violating their privacy?
