JWT Authentication

JSON Web Tokens (JWTs) are a popular and secure way to implement authentication and authorization in web applications. They are a compact, self-contained way to securely transmit information between two parties, typically a client and a server. JWTs are often used in web APIs to verify the identity of users and to grant them access to protected resources.

What are JWTs?

JWTs are composed of three parts, separated by periods (.). The first part is the header, which contains information about the token, such as the algorithm used to sign it and the type of token. The second part is the payload, which contains the claims, or data, that the token conveys. The third part is the signature, which is used to verify the integrity of the token.

How do JWTs work?

JWTs are typically issued by a server as a response to a successful authentication request. The JWT contains information about the user, such as their username, email address, and roles. When a user makes a request to a protected resource, the server can verify the JWT to confirm the user's identity and authorization.

Why use JWTs?

There are several benefits to using JWTs for authentication and authorization:

• Security: JWTs are digitally signed, which makes them difficult to forge or tamper with.
• Compactness: JWTs are compact and can be easily transmitted in HTTP headers or URL parameters.
• Stateless: JWTs are stateless, which means that they do not require the server to maintain any session state.
• Extensibility: JWTs can be used to convey additional information, such as user preferences or roles.
