Web: JWT Authentication
JSON Web Tokens are everywhere in modern authentication — stateless, compact, and easy to misuse if you don't understand what's actually inside one. This quiz tests the fundamentals.
Questions cover the three parts of a JWT, how expiration claims work, where tokens should (and shouldn't) be stored on the client, and the security risks of handling them carelessly.
Know what's actually inside a JWT — and why you should never trust an unverified signature? This quiz checks it.
