# VPN on ChromeOS

VPN access on ChromeOS allows users to securely connect to the internal university network from a Chromebook. 

## Implementation Method
Because ChromeOS supports Android applications, the university implements VPN access via the Android subsystem. Users must install the **OpenVPN Connect** app from the **Google Play Store**.

## Authentication Requirements
To establish a connection, the following credentials must be provided:
- **URZ Account**: The user's central university username and password.
- **User Certificate**: A valid [[nutzerzertifikate]] in the form of a [[p12-file]]. This certificate must be imported into the system settings before the VPN profile can be fully activated.

## Configuration Workflow
1. **App Installation**: Install and initialize **OpenVPN Connect**.
2. **Certificate Import**: The `.p12` file is imported into the Android system as a "VPN & App User Certificate."
3. **Profile Import**: A university-provided VPN profile is imported into the app.
4. **Linking**: The user enters their URZ credentials and selects the imported certificate to complete the secure tunnel configuration.

## Connection Management
- **Activation**: Triggered by the toggle switch in the OpenVPN Connect app, requiring the URZ account password.
- **Deactivation**: Triggered by the toggle switch to disconnect from the university network.
