# Passcode

Saving any sensitive data on a device without a lock / passcode makes them more prone to theft. With no user authentification device can be accessed and modified with minimal effort. freeRASP checks if the device is secured with any type of lock.

Below are code snippets demonstrating passcode detection across various platforms:

```dart
// Android lock check
override fun onUnlockedDeviceDetected() {
    TODO("Not yet implemented")
}

// iOS lock check
case passcode

// Flutter unlocked device and passcode detection
onPasscode: () => print("Passcode not set")

// Cordova unlocked device and passcode detection
passcode: () => {
    // Place your reaction here
}

// React Native unlocked device and passcode detection
passcode: () => {
    // Place your reaction here
}

// Capacitor unlocked device and passcode detection
passcode: () => {
    // Place your reaction here
}
```

{% hint style="info" %}
**Recommended action:** Log the event on your BE or react to it if you need users to have a screen lock set up, otherwise ignore it.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.talsec.app/freerasp/freerasp/wiki/threat-detection/passcode.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
