Want to lock WhatsApp chats and keep specific conversations private? The Chat Lock feature lets you protect important chats so they stay hidden from anyone who might use your phone. This guide explains how to lock WhatsApp chats on both Android and iPhone in 2026.
Whether you share your device with family members or simply want extra privacy, locking chats is one of the most useful security options WhatsApp offers.
What Is WhatsApp Chat Lock?
Chat Lock allows you to secure individual conversations with a fingerprint, face unlock, or device password. Once locked, those chats move to a separate Locked Chats folder and require authentication to open. This feature works on both Android and iPhone.
Locked chats also stay hidden from the main chat list, notifications can be customized, and the content remains protected even if someone unlocks your phone.

- Tap the contact or group name at the top to open the chat info screen.

- The chat will move to the Locked Chats folder.
You can also long-press a chat in the main list, tap the lock icon at the top, and confirm.
