hi there while changing password with terminal/bash, it accepts tab and arrow keys along with characters,symbols and spacebar. But when we try to login into the system *"TAB and ARROW key" *perform their own usual task. So we can't enter the password and it tells that password is incorrect.i tried it with ubuntu and kali linux and i got the same problem. i reported this problem to ubuntu and kali linux. kali linux replied me that its not their problem. i am forwording that mail to you.
thanks.
