Over the past few months, WhatsApp has rolled out a bunch of new updates for both Android and iOS. One of these new updates lets you add a fingerprint lock to WhatsApp. This means that you can’t access WhatsApp chats without unlocking the app via a fingerprint saved on the phone. Of course, you need a smartphone with a fingerprint sensor for this to work and the latest version of WhatsApp. Fingerprint lock on WhatsApp for Android works with phones that have a capacitive fingerprint sensor, and those that have an in-display fingerprint sensor. In this article, we will describe how to add a fingerprint lock to WhatsApp on Android.
Now, this feature has been available on WhatsApp for iPhone since February this year, and it first appeared in a beta build for WhatsApp’s Android users back in August.
How to set up fingerprint lock on WhatsApp for Android
Before proceeding, make sure you have installed WhatsApp version 2.19.221 or above by heading over to the WhatsApp page on Google Play. Once that is done, simply follow these steps to secure your WhatsApp chats on Android with fingerprint authentication.
1. Open WhatsApp > tap the vertical three dots icon on the top-right and go to Settings.
2. Go to Account > Privacy > Fingerprint Lock.
3. On the next screen, turn on Unlock with Fingerprint.
4. Additionally, you can also set the duration after which you’ll have to use your fingerprint to unlock WhatsApp. It can be set to Immediately, After a minute or After 30 minutes.
5. Further, you can also choose if you want to show the message content and sender in the notifications or not.
Now whenever you open WhatsApp, depending on the automatic lock duration you’ve set, you will need to apply your fingerprint to unlock the app. And that’s how you can set WhatsApp fingerprint lock on your Android smartphone.
