Authorization Header
The HTTP header that carries auth credentials with a request
Core Idea
The Authorization header is the standard HTTP header for carrying credentials such as access tokens. A server reads it to decide who is making the request or what permissions that request should have.
Why It Matters Here
Mathbong uses the Authorization header across FastAPI protected routes, OAuth2 token flows, and frontend auth requests. It helps learners see token auth as "the client carries an ID card on each request" rather than as a hidden browser mechanic.
