WhatsApp, the largest instant messaging application, has introduced its best chat security feature called "Chat Lock" so far, allowing users to keep some of their chats extremely private or confidential.

Although end-to-end message service is already available on WhatsApp, the application has now introduced the "Chat Lock" feature to further secure chats.

WhatsApp has announced in its blog post that the "Chat Lock" feature is being rolled out to users from May 15th, allowing users to keep their favorite chats private or confidential.

Under this feature, a new window will be created for Facebook Chat, similar to the Archive Tweet, and no third party will be able to access this chat window.

According to the blog post, users can include some of their chats in "Chat Lock" and also keep the "Chat Lock" window secured with a separate password.

Generally, some users' mobile phones are accessible to their family members or very close friends, which results in other people having access to all their chats.

However, the new "Chat Lock" feature will eliminate the concerns of such users, allowing them to keep their highly personal chats private or confidential.

Although the mentioned feature has been introduced immediately, not all users have instant access to it, and users worldwide will gradually gain access to it.

The "Chat Lock" feature is being hailed as Facebook's best security chat feature so far.

Whatsapp Chat Lock Tricks

With the increasing reliance on messaging apps for communication, privacy, and security have become major concerns. 

Whatsapp, one of the most popular messaging apps worldwide, offers various features to enhance the security of user data, including the ability to lock individual chats. 

In this article, we will explore the methods and best practices to lock Whatsapp chats effectively.

Importance of Privacy in Messaging Apps

Messaging apps have revolutionized the way we communicate, allowing us to connect with friends, family, and colleagues instantly. 

However, the sensitive nature of our conversations requires us to prioritize privacy and ensure our messages remain confidential.

Protecting Whatsapp chats from unauthorized access is crucial to safeguard personal information, sensitive discussions, and private media shared through the app.

Understanding Whatsapp Chat Locking

Whatsapp provides users with the option to lock individual chats, adding an extra layer of security to prevent unauthorized access. 

When a chat is locked, it requires additional authentication before the contents can be viewed. 

This feature is particularly useful in scenarios where you share your device with others or want to protect specific conversations from prying eyes.

Methods to Lock Whatsapp Chats

App Locking Features

Many smartphones come with built-in app locking features that allow you to secure Whatsapp and other applications with a PIN, password, or biometric authentication.

By enabling app locking, you can ensure that Whatsapp and its chats remain inaccessible without the correct credentials.

Using Third-Party Apps

If your smartphone lacks native app locking features, you can opt for third-party apps specifically designed to lock individual apps. 

These apps offer advanced security options, such as pattern locks, fingerprint authentication, and even stealth modes, providing an additional layer of protection for your Whatsapp chats.

Hidden Folders and Encryption

Another method to lock Whatsapp chats involves creating hidden folders within your device's file system. 

By moving Whatsapp media and database folders to a hidden directory, you can prevent unauthorized access. Additionally, you can encrypt the hidden folder to further enhance its security.

Biometric Security

Many smartphones nowadays offer biometric authentication options such as fingerprint scanners or facial recognition. 

By enabling biometric security for unlocking your device, you indirectly secure your Whatsapp chats as well. Only your unique biometric data will grant access to the chats.

Two-Factor Authentication

Enabling two-factor authentication adds an extra layer of security to your Whatsapp account as a whole.

 Once activated, any attempt to register your Whatsapp account on a new device will require a PIN that you set up during the two-factor authentication setup process. 

This ensures that even if someone gains access to your device, they won't be able to register your Whatsapp account on another device without the PIN.

Privacy Settings and Notifications

Whatsapp offers various privacy settings that allow you to control who can see your profile picture, last seen status, and read receipts.

 By customizing these settings according to your preferences, you can limit the visibility of your personal information and increase the overall privacy of your Whatsapp chats. 

Additionally, you can disable message previews in notifications to prevent others from reading your chats without unlocking the app.

Best Practices for Securing Whatsapp Chats

  • Regularly update Whatsapp to ensure you Set a strong lock screen password or PIN on your device to prevent unauthorized access.
  • Avoid sharing sensitive information or personal details through Whatsapp chats.
  • Be cautious when using public Wi-Fi networks, as they can be vulnerable to hacking and interception. Consider using a VPN for added security.
  • Regularly back up your Whatsapp chats to a secure cloud storage or local device storage. This ensures that even if your chats are accidentally deleted or your device is lost, you can restore them.
  • Be wary of suspicious links or attachments sent through Whatsapp. They could be phishing attempts or contain malware. Avoid clicking on them and never download files from unknown sources.
  • Educate yourself about the latest Whatsapp privacy features and settings. Stay updated on any new security enhancements introduced by Whatsapp and make use of them to protect your chats.


Protecting the privacy of our Whatsapp chats is essential in today's digital age. By implementing the methods mentioned above, such as utilizing app locking features, third-party apps, hidden folders, biometric security, two-factor authentication, and privacy settings, we can ensure that our conversations remain confidential and secure. 

Remember to regularly review and update your security measures to stay one step ahead of potential threats.
