# What is the Luffa Self-Destruct Password?

The **Luffa Self-Destruct Password** is a key feature for enhancing **privacy and security**. Once set, entering the self-destruct password when launching the app will:

* **Automatically delete all local messages**
* **Log you out of the app**\
  This helps prevent unauthorized access to your chat history. To access the app normally, simply enter your regular **security password**.

**How to Set Up a Self-Destruct Password:**

1. Go to **Personal Center**.
2. Tap **Account Security**.
3. Find and enter the **Self-Destruct Password** section.
4. Verify your identity using your **security password**.
5. Set and confirm a new **Self-Destruct Password**.
6. Tap **Enable Self-Destruct Password**.

**Important Notes:**

* **App Lock Requirement**: To use the **Self-Destruct Password**, you must first enable **App Lock**, which adds an extra layer of security by requiring a password to open the app.
* **Assets and Contacts Remain Unaffected**: Using the **Self-Destruct Password** will **not** affect your **wallet assets** or **friend list**—your funds and contacts will remain intact.
