WhatsApp is a popular messaging application with various features, including the ability to set a Fingerprint lock. Enabling the Fingerprint lock can provide an extra layer of security and prevent unauthorized access to your messages.

The process of setting up the Fingerprint lock is relatively easy, and you can follow simple steps to do so.

If you want to change your WhatsApp phone number or use a new mobile device without losing your chats, our dedicated article can be helpful.

Benefits of Using Fingerprint Lock in WhatsApp

There are several advantages of using a Fingerprint scanner in WhatsApp; let’s discuss them:

1. By enabling a biometric lock, you can secure your messages.

2. There wouldn’t be a reason to hurry even if others took your mobile.

3. Due to the uniqueness of everyone’s finger ridges, there is no chance of accessing the lock. Even twins have unique fingerprints.

4. Easy to use as it does not require any pin or password to open the app.

We can grab additional security by using a biometric fingerprint scanner.

Checking Phone Compatibility for Fingerprint Lock

IOS has had this feature for years. Luckily, Android has also launched it, but it may not be supported on older versions. The mobile device should have a touch (thumbprint) sensor to enable the Fingerprint lock feature on WhatsApp.

Remember that this feature is not compatible with some Samsung mobiles, including the Galaxy S5, Note 4, and Note 8.

Phones need to have fingerprint sensors to enable this feature on WhatsApp.

To check whether your phone is compatible with this feature, go to your mobile settings and look for the Lock Screen option. If you have a biometric signature option there, you can now use it.

How to Set Fingerprint Lock in WhatsApp from Mobile App

Enabling the Fingerprint scanner in WhatsApp from the mobile app is a pretty easy process that can be done on Android and iOS devices. Let’s go through the steps:

1. Open WhatsApp on your phone. You can download the app from the Play Store or App Store if you don’t have it.

2. Tap the three-dot option in the top right corner to access the menu. You will see various options like New group, New broadcast, Linked devices, Starred messages, and settings. From there, select Settings.

3. Find and tap “Privacy” in the Settings menu.”

4. Scroll down the screen and tap on “Fingerprint lock.

5. Enable the toggle switch button to activate.

6. You may see a message asking you to set it up on your device first. If so, go to your device Settings > Lock Screen > Fingerprints > Scan your finger and add it.

7. Tap the toggle switch back on WhatsApp and place your finger on the sensor to confirm.

Finally, you have successfully set up the Fingerprint lock on your WhatsApp account.

From now on, you’ll need to use your finger to access the app.

It’s worth noting that removing the thumbprint from your device’s settings will also be disabled on WhatsApp. A device lock is necessary to enable it.

Customizing Fingerprint Lock Settings on WhatsApp

After enabling, you’ll see a customization option below the “Unlock with fingerprint” option.

From there, you can set a specific time for the app to lock automatically. There are three options: Immediately, After 1 minute, and after 30 minutes.

Immediately will lock the app as soon as you leave it, while After 1 minute and After 30 minutes will lock it after one minute and 30 minutes of inactivity, respectively.

Another useful customization option in WhatsApp is “Show content in notifications.” When this option is enabled, you can see the preview message text in notifications, even when your phone is locked.

How do I Disable Fingerprint Lock in WhatsApp?

If you’re experiencing issues with the biometric signature in WhatsApp and want to disable it, here’s how you can do it:

1. From WhatsApp settings, tap “Privacy” and “Fingerprint lock.”

2. Now, touch the toggle button “Unlock with fingerprint” to turn it off.

Now, your finger sensor in WhatsApp is disabled.

You can enable or disable the feature anytime if you have a phone with a finger sensor.

Final thought

Enabling a Fingerprint lock in WhatsApp is a good way to secure your messages and ensure that only you can access them.

Once enabled, you must use your finger to open WhatsApp. However, you can still answer calls even if it is locked.

If you prefer not to use the Fingerprint feature, you can use a third-party app to lock WhatsApp instead.
