FHi There, you could use Keycloak as an OIDC IdP in ZITADEL or if you need more flexibilty you could use our JWT IDP (basicaly just provide ZITADEL with a JWT and the user is authenticated).
What is worth mentioning, ZITADEL will create an internal user to keep track of all the changes, sessions and so on.

FYes, that can be made work. You can use authenticate your users in KC and the forward them to ZITADEL where you can apply 2FA.
