Limitations

Key limitations: Security, redirect URLs, and provider credentials should be human-reviewed. Identity configuration, redirect URLs, provider credentials, user lifecycle actions, and permission scopes can lock users out or expose accounts if automated without review. API automation needs client-side throttling, idempotency where supported, pagination limits, retries, and audit logging. Browser automation can be brittle around UI changes, MFA, captchas, policy prompts, and hidden confirmation states.
