Mashable: Currently, Chat Lock leverages your phone's existing authentication mechanisms, such as biometrics or a PIN, and doesn't require a separate password.

WhatsApp, the popular messaging app used by billions worldwide, has introduced an exciting new privacy feature called Chat Lock. With this feature, users can protect their private conversations by hiding entire chat threads behind a dedicated password-protected folder. It's a game-changer for individuals who occasionally lend their phones to others but don't want their personal chats exposed.

Using the Chat Lock feature is a breeze. Simply navigate to the chat page of the desired user or group, tap on their name, and select the Chat Lock option. Voila! All your hidden chats will be neatly tucked away in a password-protected folder at the top of your WhatsApp inbox screen. However, it's worth noting that you'll need to pull down from the top of the inbox screen to reveal this discreet folder.

Currently, Chat Lock leverages your phone's existing authentication mechanisms, such as biometrics or a PIN, and doesn't require a separate password. However, WhatsApp has exciting plans in store for the feature. In the coming months, they will roll out updates allowing users to create a custom password specifically for the Chat Lock folder, separate from their device password. Moreover, the chat lock functionality will also extend to companion devices, ensuring consistent privacy across multiple platforms.

WhatsApp isn't stopping there. The company has exciting plans to introduce more features for Chat Lock in the coming months, including the ability to set variable passwords for individual chats. This expanded functionality will provide users with even more ways to protect their privacy within the app.

While Chat Lock may not revolutionize the WhatsApp experience for most users, its value becomes apparent in various situations. For those who share their devices, it has the potential to be a game-changer, offering peace of mind and heightened privacy.

The messaging giant recently added the long-awaited ability to edit messages on Android devices, empowering users to rectify typos and mistakes after hitting send. Additionally, WhatsApp is currently testing a version of its instant messaging app specifically designed for smartwatches running Wear OS. Furthermore, the company is partnering with Truecaller to develop a feature that will help users identify unknown callers and combat spam calls effectively.
