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. This information can be verified and trusted because it is digitally signed.

A JWT consists of three parts separated by dots (.): Header, Payload, and Signature. The header typically contains the token type and signing algorithm, while the payload contains the claims (user data and metadata).
