Authentication mechanism for OpenAI services when deploying in Dev setup in Organization

[abhattachar5]

I am working to deploy langflow studio in my organization to enable quick PoCs.
The Minimum Mandatory Safeguard policy would not allow users to enter the API key at widget level (like we do in our Local)
Two Questions:
(A) Is there a way to use the API Key as a global environment variable rather than users having to enter it in the widget in the studio?
(B) Does Langflow support other authentication mechanisms like Access Token or Auth Token which can avoid entering the API key in the widget?
