Can I use this for production-grade AI applications?

Yes, the skill is designed to implement standard OAuth 2.1 flows and middleware suitable for production environments requiring secure multi-user support.

Which authentication providers does this skill support?

It currently supports Auth0 for enterprise-grade OAuth 2.1 features (SSO, MFA) and Supabase Auth for integrated database authentication and social login.

Does this skill handle environment variable setup?

Yes, it guides you through configuring .env files for both Auth0 and Supabase, including client IDs, secrets, and public callback URLs.

How does this modify my existing server code?

The skill helps you update your server/index.ts to include authentication middleware and creates discovery endpoints necessary for the ChatGPT interface to communicate with your auth provider.

Do I need an existing Auth0 or Supabase account?

Yes, you will need an active project on either platform. The skill provides the specific steps needed to configure those dashboards to work with your app.
