# Run AWS IoT Greengrass V2 as a non-root user
<a name="run-greengrass-non-root"></a>

Typically, the root user installs and runs the AWS IoT Greengrass Core software on Linux devices. To increase device security, you can set up a non-root user to run the AWS IoT Greengrass Core software instead. This section provides guidance on setting up non-root configurations.

If you are setting up new AWS IoT Greengrass V2 core devices and want to run them as a non-root user from the start, see [Set up AWS IoT Greengrass V2 core devices as non-root](setup-greengrass-non-root.md). This guide covers multiple solutions based on your device constraints and security requirements.

**Note**  
The non-root configurations in this section apply to Linux devices only. On Windows, AWS IoT Greengrass must run as a system service.
