WhatsApp has added a new feature for private chats – the WhatsApp Chat Lock feature. It is designed to make personal conversations even more personal with an extra layer of security. Many smartphones carry a lot of private data & personal pictures/videos. Anyone with access to your device can view this personal data. While sharing a phone with a friend/ family member, you might just make your personal chats easily available to them. To help solve this problem, the new WhatsApp Chat Lock feature takes a chat out of the inbox and puts it behind its own folder. This folder can only be accessed with your device password or biometric, like a fingerprint. Watch the video to know more.
