JSON Web Tokens

JSON Web Tokens (JWT) are an open standard (RFC 7519) for securely transmitting information between parties as a JSON object. They are digitally signed using a secret or a public/private key pair, ensuring data integrity and authenticity. JWTs are commonly used for authentication and authorization in web applications and APIs.

Also known as: JWT, Json Web Token, JWT Token, JSON Web Token Standard, RFC 7519
🧊Why learn JSON Web Tokens?

Developers should learn JWT for implementing stateless authentication in distributed systems, such as microservices or single-page applications, where server-side sessions are impractical. They are ideal for scenarios requiring secure token-based access control, like API authorization, user login flows, and cross-domain authentication, due to their compact size and self-contained nature.
