Auth roadmap overview

This page is organized as an authentication learning path: start with JWT and password-hashing fundamentals, implement the full login and refresh flow, study the attack surface, then practice explaining the architecture like you would in an interview or code review.

◆ You can confidently say you know auth and can implement it from scratch.
