JSON Web Tokens (JWTs) are a compact, URL-safe means of representing claims between two parties. They are commonly used for authentication and authorization purposes in web applications. JWTs consist of three parts: a header, a payload, and a signature. The payload contains the claims, which are statements about an entity (typically the user) and additional metadata. JWTs are often used in stateless, token-based authentication systems.
