Not being able to enter password

[dl5thanniversary]

When i come to the part of entering usn&pwd(all previous steps were successfully operated), I could enter the username but I'm not able to enter the password.

You can enter the password, the input is just not visible in the terminal, as a security precaution.

Best way is to write your password into some text editor, copy it with your mouse, then go back to whenever the script asks for password and just right click once into the terminal window. It'll be copy pasting the password properly (even if you can't see it), then just press the Enter key, and you're good to go.
