Before you start: know what Google SSO protects
Google sign-in answers who the viewer is; the page access policy decides whether that identity may receive the HTML. This is different from adding a Google login button to a public static host, where the original file may still be reachable outside the application route.
- The source file remains private until the viewer passes the configured access check
- Workspace access is useful for team-wide reports
- Selected-email access is useful for a smaller review group
Authorized viewers can inspect the HTML delivered to their browser. Never embed credentials, API keys, or secrets in the report source.
