What is user sshd?

User sshd is the username associated with the Secure Shell Daemon (sshd) process. The sshd process is a secure network protocol that allows secure remote login and file transfer between computers. The user sshd is responsible for handling incoming SSH connections and managing the authentication and encryption processes. It runs as a system service and is typically found on Unix-like operating systems. The sshd user is essential for ensuring secure remote access to a system and maintaining the integrity and confidentiality of the communication.

sshd is the OpenSSH server process. It listens to incoming connections using the SSH protocol and acts as the server for the protocol. It handles user authentication, encryption, terminal connections, file transfers, and tunneling.
