Auth Change to Okta
Hey team, does anyone have any insight on how we can use the Okta sign-in page when accessing the Google Cloud (GCP) Console, instead of being redirected through Google Workspace?
We're trying to have users authenticate through Okta directly when accessing the GCP Console. Any guidance on the recommended configuration would be appreciated.

Hi @SurajB.69263 (Customer) , Thank you for reaching out to the Okta Community!
The Google Cloud Platform has a dedicated SAML implementation.
How to Configure SAML 2.0 for Google Cloud Platform
Assuming you have the implementation configured, it supports both IDP-initiated Login(start login from Okta Dashboard) and SP-initiated Login(start login from Service Provider side).
When users navigate directly to console.cloud.google.com (a Service Provider-initiated flow), Google's login architecture must perform "Home Realm Discovery." Because Google hosts millions of tenants, the platform forces users to enter their email address on a Google screen first. Only then does Google recognize that your domain is federated and redirect the browser to Okta.
You cannot completely eliminate this initial Google prompt if users type the raw GCP URL into an empty browser. However, you can bypass the Google Workspace login screens entirely by using the SP-initiated login URL, as per the above documentation:
Navigate to https://www.google.com/a/[DOMAIN]/ServiceLogin?continue=https://console.cloud.google.com.
Where [DOMAIN] is your Google domain.
For example: https://www.google.com/a/acme.com/ServiceLogin?continue=https://console.cloud.google.com
