Day 17/30: Authentication & Authorization 📌 How does your system know who you are and what you're allowed to do? Authentication answers: "Who are you?" Authorization answers: "What are you allowed to access?" Basic flow: → User logs in → Server verifies credentials → Server issues a session/token → Client sends it with future requests → Server verifies identity → Authorization checks permissions → Request is allowed or rejected Common approaches: → Sessions → JWT → OAuth 2.0 → OpenID Connect → API keys Authentication ≠Authorization Example: You successfully log into an admin dashboa
