Print asterisk instead of password (Bash)

OS : RHEL 6.5
Shell : Bash

With the following bash shell script, when I enter password, it won't be printed in the screen.
But, I would like Asterisk character to be printed instead of the real characters. Any idea how ?

Code:
$ cat pass.sh
echo "Enter the username"
read username

echo "Enter password"
stty -echo
read password
stty echo



Executing :

Code:
$ ./pass.sh
Enter the username
apuser
Enter password
$
