Reading passwords in shell script

Today One BE final year student just asked me this one on IM, for his benefit and anyone who might want to have a password wrapper(if at all!!) here it is how to do the same via a shell script,

#!/bin/sh
###This is a simple bash screipt to read password###
######without echoing the same on console#####

actual="deburocks!"
failed=0
while [ $failed -le 3 ]
do
read -s -p "Password: " userpasswd
echo ""
if [ "$userpasswd" == "$actual" ]
then
echo "Password accepted"
read
exit 1
else
echo "Sorry! Wrong password, Try again..!!"
fi
failed=$(( $failed + 1 ))
done

Please remember - 'stty' can also do the trick as below:

stty -echo
read password
stty echo

Enjoy!!
