Authentication and authorization are two different problems that most tutorials conflate. Here is the mental model, threat landscape, and FastAPI security toolkit you need before writing a single line of auth code.
9 min readAPI keys are the most misused auth mechanism in production. Here is how to generate, scope, rotate, and rate-limit API keys in FastAPI — with the patterns that separate toy projects from production systems.
9 min readJWTs eliminate session storage but introduce revocation challenges. Here is how to build access tokens, refresh tokens, and token rotation in FastAPI — with the security pitfalls that tutorials never mention.
10 min readPassword hashing is not security — it is one layer. Here is how to build registration, login, session management, and brute-force protection in FastAPI without the mistakes that lead to credential breaches.
12 min readOAuth 2.0 is not authentication — it is authorization. Here are the four grant types, why PKCE is now mandatory, and how to implement the authorization code flow in FastAPI with working code and sequence diagrams.
9 min readEight authentication and authorization methods, one decision tree. Here is the comparison matrix, production combination patterns, and pre-launch security checklist that turns auth knowledge into shipping decisions.
