Here's how you can lock WhatsApp on your phone

Although all texts, chats, and video call on the popular messaging app, WhatsApp are end-to-end encryption and nothing can be intercepted or monitored, but it is possible to make the app even more secure.

WhatsApp can be made more secure by protecting the app itself with whatever biometric security your phone has, such as fingerprints or Face ID. This way, even if someone gets physical possession of your phone, your WhatsApp messages will remain secure.

Below is the procedure explained that how you can lock WhatsApp on your Android and iPhone.

How to lock WhatsApp on Android

You can use your Android phone’s fingerprint reader to ensure only you can open the app.

1. Start WhatsApp on your Android device.

2. Tap the three-dot menu at the top right of the screen and then choose Settings.

4. Tap Privacy.
