Introduction
WhatsApp has transformed the way we communicate, offering instant messaging, voice calls, and video chats across the globe. With billions of users, privacy has become a top priority. Over the years, WhatsApp has introduced end‑to‑end encryption, two‑step verification, and biometric locks to keep conversations secure.
Recently, WhatsApp rolled out a Chat Lock feature—a powerful tool that lets you protect specific conversations with a fingerprint, Face ID, or PIN. This ensures that even if someone has access to your phone, they cannot open your most private chats without your authentication.
In this guide, we’ll cover everything you need to know about WhatsApp Chat Lock: how it works, how to enable it on Android and iPhone, how to unlock hidden chats, and what to do if the feature isn’t showing.
What Is WhatsApp Chat Lock?
Chat Lock is a privacy feature that allows you to secure individual or group conversations with biometric authentication or a passcode. Once locked, these chats are moved into a separate “Locked Chats” folder, hidden from the main chat list.
- Difference from App Lock:
- App Lock secures the entire WhatsApp application.
- Chat Lock secures specific conversations only.
- Key Benefits:
- Protects sensitive conversations from snooping.
- Hides notifications (they appear as “WhatsApp: 1 new message”).
- Allows normal WhatsApp functionality while keeping private chats hidden.
