 To authenticate, you will need a [service account](https://docs.stackit.cloud/platform/access-and-identity/service-accounts/). Create it in the [STACKIT Portal](https://portal.stackit.cloud/) and assign the necessary permissions to it, e.g. `project.owner`. There are multiple ways to authenticate:
