FastAPI Azure Auth

Tightly coupled to Azure's ecosystem; switching to another identity provider would require significant code changes and reimplementation of auth logic.

Requires precise Azure app registration and setup, with the README advising users to follow the documentation exactly first, indicating a steep learning curve for Azure novices.

Does not support simpler authentication methods like API keys or basic auth out of the box, forcing OAuth2 overhead even for basic use cases.

Relies on Azure's endpoints for token validation and config loading, which can introduce network latency and potential downtime risks compared to self-contained solutions.
