Masking user input in sh script?

Hi, I have a question, I am writing a script that would accept username and password from the user, and do somethign with it.. My problem is that when I do

read username

to read what the user wrote, it also shows on the screen what they are typing. How can I make it so that it would not show on the screen what the user is typing? (or mask it with * or something?)

Code:

stty_orig=`stty -g` 
stty -echo 
read secret 
stty $stty_orig

You can turn off the echo on the terminal.

Code:

#!/bin/bash
echo -n "login: "
read user
echo -n "Password: "
stty -echo
read pass
stty echo
