# ONC File

An **ONC (Open Network Config)** file is a configuration file format used by **ChromeOS** to automate the setup of network connections.

## Usage in eduroam Setup
In the Universität Greifswald environment, the [[easyroam]] service can generate an ONC file specifically for ChromeOS users. This file contains the necessary security certificates and network parameters required to connect to [[eduroam]] without manual entry of complex WPA2-Enterprise settings.

The file is imported into the device via the `chrome://network` interface.
