Imagine your WhatsApp chats are like a private diary. Wouldn’t it be great if only you had a key to open it? That’s exactly what WhatsApp’s Chat Lock does. It hides your chosen chats in a secret folder that only you can open—using your fingerprint, Face ID, or a secret code. This guide will walk you through everything you need to know, step by step, in a friendly way you’ll love.
Why Use Chat Lock?
- Extra Layer of Privacy
Even if someone opens your phone, they can’t see the locked chats—just “WhatsApp: 1 new message.” - Lock Only What You Want
You can lock just one chat or group without locking the whole app. - Hidden Chats Stay Hidden
When using the secret code, the Locked Chats folder doesn’t even show up—unless you type the code in the search bar.

FAQs
Do notifications still show up for locked chats?
Yes. But they’re discreet. Instead of showing message previews or names, they just say “WhatsApp: 1 new message.”
Will locked chats stay locked if I switch phones?
Yes. If you back up and restore your chats on a new phone, the locked chats stay locked—just make sure you’ve enabled device authentication.
What if I want to unlock a chat later?
Open the Locked Chats folder, choose the chat, tap its info or menu, select “Unlock Chat,” then authenticate. It moves back to your main list.
What if I forget my secret code?
You’ll need to reset chat lock settings in your privacy menu, which will remove the code and unlock your chats.
Can group chats be locked too?
Yes, group chats can be locked just like one-on-one chats.
