## Something else?

Any library that supports OpenID Connect discovery and the authorization code flow with PKCE works with OneiD. Give it the OneiD address and your client ID. The [Connector specification](https://oltinid.com/docs/ai/connector-specification/) lists everything a library or product must do.
