Free OAuth providers vs paid domains for AI tool access?
Understand why free identity providers expose more risk than paid domain-based delegation for AI integrations.
What you are probably seeing
You grant a free OpenID provider broad permissions to speed up onboarding, and your team loses track of which agents hold active sessions across accounts.
Paid domain registrars offer scoped credentials, but you see no clear guidance on limiting agent access to specific services rather than whole workspaces.
Why it happens
Free identity services default to broad token scopes to simplify integration, leaving no easy way to restrict access per tool or per team.
Domain-based delegation ties permissions to organizational structure, but many operators skip scoping steps because setup feels less urgent than getting tools running.
What changed recently
Step by step
1. Audit all free OAuth and OpenID connections and list which agents hold read-write access to shared accounts.
2. Request scoped API keys from vendors that integrate with your domain registrar or workspace provider.
3. Disable domain-wide delegation for external AI tools and assign each agent the minimum service scopes needed for its task.
4. Set up separate service accounts for each AI tool and map them to specific domain registrars or workspace projects.
5. Schedule a weekly review of active agent credentials and revoke any that exceed their defined scope or expiration date.
