Locking a conversation on WhatsApp

Locking a conversation is the WhatsApp feature that moves a chat into a protected folder, only accessible with the device's password or biometrics. The conversation disappears from the main list and its content stops showing in notifications.

What changes when you lock it

1. The conversation leaves the main list and moves to "Locked chats."
2. Notifications hide the sender and content — only a generic notice shows up.
3. Access requires authentication, which can include a secret code.
4. Media stops saving automatically to the gallery.

Limits and things to watch

• It does not notify the other person. Nobody knows it was locked.
• It does not delete or archive anything. The messages stay there and keep arriving.
• It can use a secret code different from the phone's password. Check which authentication is set up before sharing the device.
• It does not sync as a business security feature. The feature controls access to conversations, not a team's support permissions.

Where to find it and how to open it

On the phone, swipe the conversation list down and open Locked chats. If the folder is hidden, type the secret code into the search bar. On WhatsApp Web, accessing locked chats uses a secret code created on the main phone.

Unlocking is not clearing

To show a chat again, use Unlock chat. The Unlock and clear chat action deletes messages and media from protected chats; it is not an equivalent shortcut. If you forgot the code, read the recovery conditions before confirming any clearing.

What about team support?

Before sharing a work number, define who can access the conversations, who handles each customer, and where to log progress. Locking a conversation does not create a queue, does not assign an owner, and does not define a support process.

If the need is organizing a team, see the concept of multi-agent support and compare the permissions the tool you chose offers. For personal privacy, use WhatsApp's own settings.

In a team, what protects the customer's conversation is a centralized history with individual logins, not a lock on a phone — see CRPRO's multi-agent support.
