Matrix + Authentik (OIDC)

I have Synapse server (Matrix) running locally, but I have it configured to use OIDC integration with my Authentik SSO instance (along with all my other local services).

I’d love to have a room for updates from Home Assistant, but in the YAML configuration it looks like only username/password authentication is supported.

I already created a Matrix user specifically for Home Assistant to use, but it sounds like I would need to re-enable password authentication in Synapse to support this (which kind of defeats the purpose of SSO). Am I missing something? Perhaps I’m going about this the wrong way?
