use while read

try

while read ANYNAME
do

echo ${ANYNAME}
#each line will be stored in this variable 1 at a time
*****
done < xxxx.txt

Try the "FOR Loop..."

you can use the below FOR loop.
If you have only password in the xxxx.txt, then this will help.
Otherwise you need to cut to get the value stored, into the passwd variable.

#########################
for x in `cat xxxx.txt`
do
passwd=$x
#
#your processin will come here.
#
done
#########################

Please revert if u hv any concerns.

Best Regards,
