What does JWT stand for in JWT Bearer authentication?

• A. Java Web Token
• B. JSON Web Token
• C. Justified Web Token
• D. JavaScript Web Token

Answer: (B)

In JWT Bearer authentication, JWT stands for JSON Web Token. This refers to a standardized format for securely transmitting information as a JSON object between parties. The information contained within the token can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA or ECDSA. The use of JSON makes the token relatively lightweight and easy to parse, which is particularly advantageous in web applications where performance and interoperability are critical. This format has become a popular method for authentication and information exchange across various platforms and services due to its efficiency and convenience in a stateless context, where maintaining session state on the server side may not be ideal. Understanding this concept is essential for developers who implement authentication mechanisms, allowing them to securely handle user sessions and data exchange in their applications.
