We have SAML based SSO enabled between Google and Okta and would like to maintain service accounts on Okta side (not on Google). Does Okta support Google Application Credentials? These would allow us to move service accounts with admin priveledges to Okta w/o need for admin level access to G-Suite. https://developers.google.com/identity/protocols/application-default-credentials
From the link that you sent, it looks like this is functionality for OAuth 2.0, not SAML. With further understanding of the exact Use Case you are trying to accomplish, we might be able to accomplish this via the Okta OAuth 2.0 features that we offer. https://developer.okta.com/standards/OAuth/index https://developer.okta.com/docs/api/resources/oauth2.html
I would recommend opening a case with our Dev Support team in order to further dive into the issue to see if the possibility of using Okta OAuth will meet your Needs.
