How to "lock" WhatsApp conversations and prevent unwanted access

Nobody wants other people to have access to their private conversations. For those who suspect that someone may read messages sent to family, friends or colleagues, WhatsApp offers features that help reinforce privacy.

One of the available options allows you to block access to the application with biometrics. This way, conversations can only be opened after identification by fingerprint or facial recognition.

The tool is available for Android and iPhone cell phones and allows you to choose how often authentication will be requested. The user can determine that unlocking is required immediately after closing the application, after one minute, or after 30 minutes.

You can also decide whether the content of messages will continue to appear in notifications. When this option is activated, the sender's name and part of the text received can be displayed on the cell phone screen, even with the application locked.

How to lock WhatsApp with biometrics

Open WhatsApp and tap the three dots icon in the top right corner of the screen.

Then, access “Settings” and enter the “Privacy” section.

Scroll down until you find the app lock option and activate biometric unlocking.

Confirm your identity using the fingerprint or facial recognition registered on the device.

Then, choose when authentication should be requested: immediately, after one minute or after 30 minutes.

In the same area, the user can also define whether the content of messages will be shown in notifications.
