How do JSON Web Tokens work?

Question

How do JSON Web Tokens function?

Answer 1

JSON Web Tokens offer a secure and concise way for two parties to exchange information. The token is made up of three components: the header, payload, and signature. Typically, the header outlines the type of token and cryptographic algorithm used to secure it, while the payload contains the actual data being transferred. The signature is used to verify the authenticity of the message and ensure it has not been tampered with. Once a user logs into a system, a JWT is generated and given to the client, which can be used for future requests to access protected resources without requiring the user to authenticate again.
