Telnet is used most often for remote management but also sometimes for the initial setup for some devices, especially network hardware such as switches and access points.

Telnet is also used to manage files on a website. Telnet originally was used on terminals. These computers require only a keyboard because everything on the screen displays as text. The terminal provides a way to remotely log on to another device, just as if you were sitting in front of it and using it like any other computer.
