Is authentication through OIDC supported in Okta Org2Org?

Authentication through OpenID Connect (OIDC) is not supported in an Okta Org2Org configuration. This limitation stems from the way Okta's security framework is structured, which emphasizes the use of OAuth 2.0 flows for authorization between different Okta organizations. In typical use cases for Okta Org2Org communication, OAuth 2.0 is utilized primarily for resource access where identifiers and access tokens are handled differently compared to traditional OIDC, which focuses more on securing user authentication and identity verification.

While Okta does provide integration capabilities for different use cases, when it comes to directly authenticating users from one Okta organization to another using OIDC, the framework does not support this approach. Consequently, any attempts to leverage OIDC in an Org2Org setup would not function correctly, as it doesn't align with the intended use of the protocol in such scenarios.
