In May 2023,WhatsApp introduced Chat Lock, adding a handy new way to safeguard your private chats from prying eyes. The feature lets you lock important conversations behind your phone’s PIN/password or biometric authentication. Then, in December 2023, WhatsApp improved Chat Lock byadding a secret lock functionality, ensuring you can move your private chats to a hidden inbox protected with a secret code. The problem with Chat Lock is that it only works on the primary device, with the hidden chats still visible on your linked devices. It appears WhatsApp is working on addressing this limitation of Chat Lock for linked devices.
How to use WhatsApp Chat Lock
Secure your privacy over WhatsApp with this handy feature
In the latest WhatsApp beta for Android v2.24.8.4,WABetaInfodiscovered the option of accessing locked chats on linked devices. To access the hidden chat box from one of your paired devices, you must have a secret code set up via your primary phone.

Once this feature rolls out, you can access your hidden chats from any of your linked devices. Currently, your locked chats are not hidden on other devices besides your phone, posing a significant privacy risk. Given the popularity of multi-device support in WhatsApp, this is a major drawback in Chat Lock’s current implementation.
WhatsApp has been working on chat lock support for linked devices for some time now. Given the latest development, the feature should roll out in beta and eventually to the public channel sooner rather than later. Once this improvement rolls out, it will address one of ourmajor complaints about WhatsApp’s linked device implementation.
