Secure Shell or SSH is a communication protocol for operating network services securely. It helps to connect two computers remotely over an open network such as the internet.
In WordPress, SSH is used to access a website’s server through a command line interface. This allows developers and administrators to perform various tasks, such as installing updates or managing files, without having to use a graphical user interface.
SSH is often preferred over other protocols, such as FTP or SFTP, because it provides a higher level of security and encryption.
