How to lock your WhatsApp: protect your chats with a password or fingerprint

To block your WhatsApp you just have to enter the application and choose the fingerprint lock (in the case of Android phones) or Touch ID (for iOS devices). Another way to protect your conversations is by blocking the app from the phone’s settings. If none of these options is available on your Smartphone, then you can protect the chats by installing a mobile app that requests a PIN or pattern every time you go to WhatsApp.

It is important to lock the phone so that no external person can review the conversations without prior authorization. If for some reason, that person knows the password or the initial pattern, then it is advisable to strengthen the security of the other applications by blocking each one. Therefore, in this article you will see how to block WhatsApp from both an Android and an iOS device.

From Android
