What is a JWT?
A JSON Web Token (JWT) is a compact, URL-safe way to represent claims between parties. It consists of three parts separated by dots:
- Header: Contains the token type and signing algorithm
- Payload: Contains the claims (user data, expiration, etc.)
- Signature: Verifies the token hasn't been tampered with
