What is SSH?

SSH is like a secret tunnel that lets you control a computer from far away [4]. Instead of sitting at the keyboard, you can type commands on your computer and they get sent safely through the internet to another computer [4].

Why is it useful?

Imagine you have a computer at home and you're at work—SSH lets you access it securely without anyone being able to spy on what you're doing [4]. It's like having an invisible, locked door only you can open [4].

How do you start using it?

First, you need to open a command line program (like PowerShell on Windows) [2]. Then you tell your computer to connect to another computer using SSH, kind of like dialing a phone number [2].

What do you need?

You need to know the address of the computer you want to connect to (called an IP address) [1] and usually a username and password, like logging into a website [2].
