Just had a call with @kkiani , it seems that this issue needs to be rephrased.

The goal is to introduce a mechanism to authenticate users / applications that is in line with the OpenAI specification, which uses an API key. This way, it can be cloud agnostic and not depend on e.g. Cognito user pools.

Closing this as this is implemented and integrated.
