SSH is usually used to access servers running Unix-like operating systems, but your own computer doesn’t have to be running Unix in order to use SSH. You normally use SSH from your computer’s command line in a terminal by typing a command such as ssh <a href="mailto:username@example.com">username@example.com</a>, especially if your own computer runs Linux or macOS. After logging in, you’ll have access to the server’s command line. If you use Windows on your computer, you might also use a dedicated SSH application such as PuTTY. Most Certbot users run Certbot from a command prompt on a remote server over SSH.</p> <div class="bottom-text"> <a href="/glossary">From our Certbot Glossary</a> </div> </div> </div> <br/> with the ability to <div class="glossary-term js-only disabled"> <a class="glossary-link js">sudo</a> <div class="tooltip js"> <div class="close-button"><img alt="Close button" class="close-tooltip" src="/assets/close-d50a57de0821395c65cd8330305a71fa397a0a8dc4eaed6aa367ae13eca315d8.svg" /></div> <div class="tooltip-title"> <a href="/glossary#sudo">sudo</a> </div> <div class="mobile-hidden"> <p>Sudo is the most common command on Unix-like operating systems to run a specific command as root (the system administrator).
