Daily Term: JSON Web Token

JSON Web Token

JSON Web Token (JWT) is a compact, URL-safe standard for securely transmitting information between parties as a JSON object. It consists of three parts—Header, Payload, and Signature—encoded in Base64 and separated by dots. JWTs are often used for authentication: after a user logs in, the server issues a JWT, which the client includes in subsequent requests to verify identity. JWTs are stateless and scalable but require careful handling to prevent security issues like token theft.
