For Google Workspace SSO support, the best choice is usually SAML 2.0.
Why SAML 2.0
- It’s the standard Google Workspace uses for enterprise SSO.
- Works well with most identity providers like Okta, Azure AD, OneLogin, Ping, etc.
- Good fit if you want hosted login, single sign-on, and centralized user management.
When to use something else
- OpenID Connect (OIDC): better if you’re building a modern web/mobile app and want a simpler integration.
- OAuth 2.0: use for API authorization, not for SSO itself.
Practical recommendation
- If you’re integrating a business app with Google Workspace: use SAML 2.0 for SSO
- If you’re building an app that signs users in with Google accounts directly: use OIDC with Google Identity
If you want, I can also help you decide between SAML vs OIDC for your specific app.
