authentik CTO here; we’ll fix this in the next release (match-april), it should be possible in a non backwards incompatible way using the suggestion in this comment https://github.com/goauthentik/authentik/issues/6139#issueco... (which does call that solution a hack but I wouldn’t necessarily agree)
Authelia has a very unique advantage of its small footprint, which is something that neither Keycloak nor authentik (which I work for as a disclaimer) can really fit into. It’s a very good usecase for a homelab environment and if you don’t need/want features of the “bigger” solutions!
