 that has limited permissions. The need for machine user accounts is especially important for GitOps deployment flows with projects like [Flux](https://docs.github.com/en/developers/overview/managing-deploy-keys#machine-users)
 and [ArgoCD](https://github.com/argoproj/argo-cd). These tools need an authentication method that supports accessing multiple repositories, without sharing the global credentials with all users.

 specific to a Git repository. These tokens are then written to a Kubernetes secret in the Kubernetes namespaces which should have access to the repositories. When a repository is cloned through the
