Hmm, the SSO is too cumbersome with me (I don't want to set up my own OpenID service just for this). The preauth key might work though. I'll try it out!
why im still using keycloak
But nothing against keycloak - keycloak is the gold standard. But compared to Authelia, Keycloak is really cumbersome to get up and running and also to maintain.
I would need more security keys but it sounds like there is a non-gui method? That'd be fine for me.
