What is JWT?

JWT, or JSON Web Token, is a compact and secure way to transmit information between parties as a JSON object. It is commonly used for authentication and information exchange in web applications. A JWT consists of three parts: a header, a payload, and a signature. The header typically specifies the type of token and the signing algorithm used. The payload contains the claims or information about the user, such as their ID and roles. The signature is created by combining the encoded header, payload, and a secret key, ensuring that the token cannot be altered without invalidating it. When a user logs in, the server generates a JWT and sends it back to the client, which then includes it in the header of subsequent requests. This allows the server to verify the user's identity without needing to store session information, making it efficient and scalable. In the software development cycle, JWTs are often integrated during the authentication phase, allowing developers to create secure applications that can easily manage user sessions. Developers who work with JWTs focus on implementing secure authentication mechanisms, ensuring that tokens are generated, validated, and stored properly, while also protecting sensitive user data.
