## What it is
A tutorial repository teaching how to use JSON Web Tokens (JWT) for authentication in web and mobile applications, with working examples and tests in Node.js/JavaScript. It explains JWT structure, signing, and usage for securing apps and APIs.

## Use cases
- learn how json web tokens work
- secure a node.js web app with jwt authentication
- understand jwt token structure and signing
- example of token-based authentication with tests
- how to authenticate users in a web or mobile app with tokens

## When to choose
- you are learning JWT authentication concepts from scratch
- you want a tested, working Node.js example of token-based auth
- you need a plain-English explanation of how JWTs secure web apps

## When to avoid
- you need a production-ready authentication library or service rather than a tutorial
- your stack is not JavaScript/Node.js
- you need advanced JWT features like refresh token rotation or OAuth2/OIDC flows

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: auth, security, developer-tools
- domain: security, web-development, tutorials
- platform: -
