A particularly useful tool is the message preview in notifications, which allows users to read incoming messages without opening the application.

However, this convenience can occasionally compromise privacy, especially when messages are visible on a device's lock screen to anyone nearby.

To address this privacy concern, WhatsApp provides a method to disable message previews.

Users can implement this security measure by navigating to

·        Settings

·        Privacy

·        App Lock via the three-dot menu in the top left of the app.

By enabling biometric authentication (fingerprint or face ID), users gain access to the Content Notifications option, which can then be toggled off.

Once disabled, WhatsApp messages will no longer display on the lock screen or within general notifications, thereby securing users’ conversations.

This feature is particularly valuable for individuals who frequently handle sensitive information on their mobile devices.
