Hi team, we have an existing user management system, can we use it together with Hydra to support SSO, or we have to use kratos together? I don’t find any hydra document mentioning much on SSO.

Hello @early-queen-73010 Yes you can use Ory Hydra standalone as OAuth2 / OIDC server. What exactly do you mean when you say SSO? “Login with $ACME” through OIDC? Federation of accounts for multiple domains? Basically what is it that you want to achieve by using Ory?
