# How to turn on the App passcode

In order to increase your Coinplus data security, you can set a passcode lock on your app, and it will ask for the passcode every time you enter the app. If your device supports biometric authentication(Face id, Touch id), you can use your it as well instead of your passcode.

It's **highly recommended** to always turn on the passcode on the app. 

**Step 1**

* Go to the **Settings tab**
* Enable the **App lock**

Biometric authentication will be turned on by default.&#x20;
