Section 1
The big idea
JWTs are how most modern apps stay logged in. They look like garbled strings but encode user info. AI can decode them, explain expiration, and warn you what NOT to put in them.
Some examples
- Ask AI to decode a JWT and show the payload
- Ask AI why you should never put passwords in a JWT
- Ask AI to add token refresh logic
- Ask AI to set safe cookie flags
Try it!
Grab a JWT from a dev tool (yours, not someone else's). Paste only the structure to AI. Ask it to explain each part and what makes the token 'valid'.
