Add optional ChatGPT Codex integration with OAuth support

[bytes-Knight]

Hi 👋

First of all, great work on rep-chrome — really useful extension.

I wanted to ask if there are any plans (or if it’s technically feasible) to add ChatGPT Codex integration using OAuth-based authentication instead of API keys.

Why this would be useful

• OAuth avoids users hardcoding or exposing API keys
• Better UX for non-technical users
• Easier token rotation and permission handling
• Aligns with modern extension security practices

Possible approach (high-level)

• Use OAuth flow handled by a backend or trusted auth proxy
• Store access tokens using Chrome extension storage APIs
• Allow users to opt-in to Codex-powered features (code analysis, suggestions, etc.)

I’m not asking for immediate implementation — just checking feasibility and whether this aligns with the project’s roadmap.

Happy to help with research or testing if needed 👍

Thanks!
