Which JSON object sent in HTTP requests authenticates a client?

JWT (JSON Web Token) is a compact, URL-safe means of representing claims to be transferred between two parties. It is commonly used for authentication and authorization in web applications. When a client successfully authenticates, a server issues a JWT, which the client then includes in subsequent HTTP requests (typically in the Authorization header as a Bearer token) to prove its identity and access protected resources. SSH (Secure Shell) is a network protocol for secure remote access to computers, not an authentication object sent in HTTP requests. HTTPS (Hypertext Transfer Protocol Secure) is an encrypted version of HTTP, ensuring secure communication, but it's a protocol, not an authentication object. TLS (Transport Layer Security) is the cryptographic protocol that provides security for HTTPS, also not an authentication object itself.
