I don't know if you guys know what PuTTY is,but it is like a remote desktop connection or something.Anyway,when i type in log in as AmericanServer,then it asks for pass,and when I type it doesnt show.Here is a screenie:
PuTTY does not show password input to prevent people who are looking at your screen from knowing how long your password is. It's a security feature on lots of applications that use SSH.
