It also works with Touch ID-enabled iPhones.
Privacy is definitely a major concern, especially on your smartphone. Messaging apps like WhatsApp, for example, can somehow reveal some personal details about you or the person you are talking to, which is why it’s best to keep it locked from peering eyes.
A recent update to WhatsApp enabled it to use Touch ID and Face ID on newer iPhones. This means that you can use biometrics to lock the app even when someone managed to unlock your smartphone. It’s a simple yet secure feature which should add an extra layer of protection to your private conversations.
The guide below shows how you can use Face ID and Touch ID to lock WhatsApp. Unfortunately, some Android smartphones already have a similar feature, but it’s limited to some premium devices.
1. Open WhatsApp on your iPhone and head to the Settings
2. Inside, tap Account and then choose Security
3. Once on the next menu, you can scroll down to the bottom of the page and tap Screen Lock
4. From there, you can then enable Face ID (Touch ID if you’re using a fingerprint sensor) and then choose how often it would lock the app
