I tried both voidauth and authelia and found that I really like that you can (actually must, as far as I’ve seen) configure authelias OIDC clients as configuration files. That fits a gitops style approach much better when paired with e.g. sealed secrets. It was a real pain to figure out that authelia configuration, hard agree on that… The official helm chart felt way too over-parametrized and is badly documented. The project website has a lot of basically-copy-paste configs for all kinds if self hosted software though.
