How to Use Chat Lock on WhatsApp

Maintaining the privacy and security of our conversations has become increasingly important. To address these concerns, WhatsApp, a popular messaging platform owned by Meta, has introduced a new feature called Chat Lock. This feature allows users to lock their chats with a fingerprint, adding an extra layer of protection to their private conversations. In this article, we will guide you through the process of using Chat Lock on WhatsApp, step by step, ensuring that your conversations remain secure and confidential.

How to Use Chat Lock on WhatsApp

The Chat Lock feature on WhatsApp is a privacy-enhancing functionality introduced by Meta. It allows users to lock specific chats with a fingerprint, ensuring an additional layer of protection for sensitive or confidential conversations. Locked chats are moved to a hidden folder called “Locked chats,” making them inaccessible from the main “Chats” screen. To view and interact with locked chats, users must authenticate using their registered fingerprint.

Also, notifications from locked chats still appear in the device’s notification tray but do not display sender names or message content, preserving privacy. With Chat Lock, users can maintain the security and confidentiality of their conversations on WhatsApp.

How to Get the “Chat Lock” Feature on WhatsApp

To begin using the Chat Lock feature, you need to update your WhatsApp application or enrol on the WhatsApp Beta testing program (if necessary).

Visit your device’s app store and search for WhatsApp. If an update is available, click on the “Update” button to install it. However, the Chat Lock feature is still new and may not be available after updating the app because it has not yet been rolled out to all users. To jump the queue, you need to join the Beta testing program.

If you would like to join the WhatsApp Beta testing program and install “WhatsApp Beta” for your device, follow this guideline.

How are Notifications Handled for Locked Chats

While locked chats provide an additional layer of privacy, it’s essential to understand how notifications are handled for these chats.

Notifications from locked chats will still appear in your device’s notification tray. However, these notifications won’t display the name of the sender or the content of the message they sent. This ensures that even if someone else has access to your device’s notifications, they won’t be able to see any details about your locked chats.


The Chat Lock feature on WhatsApp offers a valuable solution for users concerned about the privacy and security of their conversations. By following the steps outlined in this article, you can easily enable Chat Lock, lock specific chats, and manage your locked conversations. With Chat Lock, you can have peace of mind, knowing that your private chats are shielded from prying eyes. Update your WhatsApp today and take advantage of this powerful privacy feature.
