> JWT.IO allows you to decode, verify, and generate JSON Web Tokens.

## About

jwt.io is the go-to resource for JSON Web Tokens (JWTs). It provides:
- An interactive JWT debugger to decode and verify tokens

## JWT Overview

A JSON Web Token consists of three Base64Url-encoded parts:
1. Header - algorithm and token type
2. Payload - claims (registered, public, private)
3. Signature - ensures token integrity

Format: xxxxx.yyyyy.zzzzz
