### OpenID Connect (OAuth2)

Only use our **OpenID Connect** in case you want to act on the behalf of other users via our API, e.g building an app/service for Crosspoint customers. Otherwise, always use an **Organization Access Token (OAT)** to integrate Crosspoint for your own service.

Crosspoint implements the [OpenID Connect specification](https://openid.net/developers/how-connect-works/) to enable third-party authentication. It's a layer on top of the OAuth2 framework aiming at making integration more standard and predictable.
