WhatsApp has introduced a new Chat Lock feature that allows users to secure specific chats to protect their privacy. This feature is especially useful when sharing your device with untrusted individuals.
Additionally, WhatsApp ensures privacy by hiding the contents of locked chats in notifications. However, the Chat Lock feature has some limitations, including slow performance and a potential loophole if the locked folder is left open.
Users are advised to remember to close the folder and consider using the fingerprint lock feature for the entire WhatsApp app as a temporary solution.
