How to Enable the Fingerprint Lock Feature on WhatsApp for Android?

The fingerprint lock is a security feature that WhatsApp added for protection of privacy. Due to this feature, WhatsApp users will be able to add their phones as an authentication tool. You can follow these simple steps to enable this feature:

Step 1: Open WhatsApp.

Step 2: Tap on the three-dot icon on the top right corner to access options.

Step 3: Tap on Settings.

Step 4: Tap on Account.

Step 5: Tap on Privacy.

Step 6: Scroll to Fingerprint lock and tap on it.

Step 7: Turn on ‘Unlock with fingerprint sensor’.

Step 8: Once you do, it will ask you to ‘confirm fingerprint.’ Confirm the fingerprint.

Step 9: Select when you want your Android device to ask for the fingerprint. There are three options — immediately, after 1 minute, after 30 minutes. Right below this, you will also get an option to turn on ‘Show content in notifications’ which if enabled will allow you to preview message text inside new message notifications.
