OAuth2
A standard set of flows for token-based authorization and authentication
Core Idea
OAuth2 is a framework that standardizes how access tokens are issued after login and validated on later requests. Its practical value is that users do not need to resend their password every time the client asks for protected data.
Why It Matters Here
Mathbong uses OAuth2 as the skeleton for FastAPI authentication lessons and explains JWT as a common token format inside that flow. It helps learners think in terms of "login once, verify tokens after that."
