JSON Web Token is best described as which in the context of authentication protocols?

Explanation:
A JSON Web Token is best described as a compact, URL-safe token format used to carry authentication and authorization information between parties. It’s not a protocol itself; rather, it’s the data structure that holds claims about a user or client, such as who they are and what they’re allowed to do. A JWT is typically signed (with a shared secret or a public/private key pair), which lets the recipient verify its integrity and origin without keeping server-side session state. Because it’s self-contained, servers can be stateless and trust the token’s validity as long as it’s not expired or revoked. In practice, JWTs are often used within frameworks like OAuth 2.0 and OpenID Connect to represent access or identity tokens. Other items listed, such as OAuth, Shibboleth, or PEAP, refer to protocols or specific authentication frameworks, not the token format itself.
