OpenAI OAuth v2's new Sign in with ChatGPT button lets users securely link their free or paid ChatGPT account that your app can use as an OpenAI API. It uses a reverse-engineered version of Codex's OAuth flow under-the-hood, and authenticates directly between your browser and OpenAI's servers with the credentials passed locally through a Sign in with ChatGPT browser extension.

And, just like OpenAI OAuth v1, you can always run `npx openai-oauth@latest` to instantly get a free local OpenAI API with your Codex account.

OpenAI OAuth v2 is open source under Apache-2.0 on GitHub: https://github.com/EvanZhouDev/openai-oauth

Let me know if you have any feedback or find any bugs!

There is any risk of getting my account blocked by using this?

I would say that the risk is very low. OpenAI has allowed usage of Codex's OAuth in other AI harnesses (as per communications on X/Twitter), and this is simply generalizing that. I have personally been using OpenAI OAuth's CLI frequently since v1 months ago.

That being said, by using OpenAI OAuth, you assume the risks of using this project, and you are still responsible for complying with OpenAI's Terms of use and usage Policies. See https://github.com/EvanZhouDev/openai-oauth#legal for more information.
