# ID-Server & Key Configuration

The **ID-Server and Key configuration** is a method used by [[rustdesk]] to route connections through a specific relay server rather than the default public infrastructure. This is critical for institutional security and connectivity within a managed network.

For the **Universität Greifswald**, the configuration ensures that remote support sessions are routed through the university's own infrastructure:
- **ID-Server**: `rustdesk.rz.uni-greifswald.de`
- **Security Key**: A specific cryptographic key used to authenticate the connection to the relay server.

Without this configuration, the client may not be able to establish a connection with the [[universitatsrechenzentrum-urz]] support agents.
