About JWT
JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object.
A JWT consists of three parts:
- Header: Contains the token type and signing algorithm
- Payload: Contains the claims (user data and metadata)
- Signature: Used to verify the token hasn't been tampered with
