The Terminal will ask you for your machine's password.


When typing, don't be alarmed if you don't see your keystrokes while typing your password. Your machine is still receiving this information.

Press enter when you are finished. If you're attempting to run a command from the terminal and receive a permissions error, check if adding sudo to your command will resolve the error.
