How to hide password entry in Bourne/bash shell script

Sometimes its required in bash scripts to read a user password. We don't want to echo the password user is entering to the screen. The following shell script accomplishes that

echo -n "Enter password: "
# Save the original stty setting
stty_orig=`stty -g`

# Switch off echoing of password
stty -echo
read password

# Switch things back to normal
stty ${stty_orig}

echo ""
echo "You securely added $password"
