How to Lock & unlock WhatsApp Chat Lock || WhatsApp Hide & Secret Chat

On Android and iPhone, you can turn on the chat lock feature to add an extra layer of privacy to specific chats. In order to read or send messages, you’ll need to unlock your chats using device authentication, such as your phone passcode, Face ID, fingerprint, or with a secret code that you can set up. These chats will be kept separate from your other chats in a Locked Chats folder. When chats are locked, the notification content and contact are hidden. The notification will show as WhatsApp: 1 new message. To help keep media private, you’ll have to turn chat lock off to save media to your phone’s gallery. Group chats and muted chats can also be locked. Calls won’t be locked. A call from a locked chat contact or group will still appear. When you turn on chat lock from your phone, it will lock chats on that phone only. If you have other devices linked to WhatsApp, such as a desktop computer, the chats on those linked devices won’t be locked. If you use the backup and restore feature on WhatsApp, your locked chats will still be locked once you restore to a new phone. To access your locked chats you will need to have device authentication (fingerprint or Face ID) set up first. When you turn on chat lock, the person you’re chatting with won’t know you’ve locked the chat. If you want to lock an archived chat, you’ll need to unarchive it first, then lock it.
