I would like to use the Google Cloud Identity Platform as the SAML IdP for Auth0. I know how to do it in reverse, but I’m struggling to find a way to let Auth0 be the SAML service provider and Google be the identity provider.
Note- I’m referring to the Google Cloud Identity Platform/Firebase not the Google Workspace SAML integration.
I have done some research around this use case, and of course Auth0 can be configured as a SAML Service Provider, with step by step instructions that are mentioned in the previous link. Also Auth0 supports any type of SAML Identity Providers that conform to the SAML 1.1 or SAML 2.0 protocol, but unfortunately I was not able to locate any configuration instructions that might lead to setting Google Cloud Identity Platform as a SAML Identity Provider, so most probably this feature is not yet available. You could get in touch with them directly in order to submit a product feedback.
Thank you for your post and I hope this provided useful information,
Remus
