It acts as a companion of reverse proxies by handling authentication and authorization requests. **Authelia** can be installed as a standalone service using Docker or NPM but can also be deployed easily on Kubernetes. On the latest, one can leverage ingress configuration to set up authentication and authorizations for specific services in only few seconds.
