WhatsApp already allows you to lock the app using a passcode or biometrics (fingerprint or Face ID) to prevent other people from reading your confidential messages.

This means that even if someone gains access to your WhatsApp, they will be unable to view protected chats. That being said, if you’ve been waiting for this function, let’s discover how to lock and hide WhatsApp messages on your Android and iOS phone.
