I often SSH into a machine and use sudo on it. When entering passwords, I'm always afraid that another window will steal the focus. However, I don't want to display asterisks (with pwfeedback, for example) because that would reveal the number of characters.Is there a tool available that could give a visual feedback for every character entered, without revealing the number of characters typed? Something like a pipe that rotates on key presses? Basically, anything that moves on key presses would be fine.In my particular case, this tool would need to work with both SSH and sudo. The target machine is running Ubuntu 15.10. I'm usually SSHing into it using putty from Windows 10.
