WhatsApp Chat Lock: Complete Guide to Protecting Private Conversations

Want to keep certain chats away from prying eyes — even if someone unlocks your phone? With WhatsApp Chat Lock, you can protect sensitive conversations with your device's password, fingerprint, or Face ID.

What is WhatsApp Chat Lock?

Chat Lock is a feature that lets you lock individual chats behind your phone's biometric authentication (fingerprint or Face ID) or your device password. Once locked, the chat moves into a hidden folder called "Locked Chats."

Why Use Chat Lock?

• For work-related or business chats
• For private conversations you don't want others to read
• To prevent accidental exposure during screen sharing
• If you frequently hand over your phone to others
