So, it sounds like you want something structured more like:
but, as RudiC has already said, that isn't the way the passwd utility reads passwords (it reads from its controlling terminal; not from standard input). Therefore, you're going to have to find something other than:
to set the user's password.
Does useradd on your system have an option to set a password as a side-effect of creating the account? (This is one of the many reasons why you should always tell us what operating system you're using when you start a new thread in this forum.)

passwd
PASSWD(1) BSD General Commands Manual PASSWD(1)NAME
passwd -- modify a user's password
SYNOPSIS
passwd [-i infosystem [-l location]] [-u authname] [user]
DESCRIPTION
The passwd utility changes the user's password. If the user is not the super-user, passwd first prompts for the current password and will
not continue unless the correct password is entered.
When entering the new password, the characters entered do not echo, in order to avoid the password being seen by a passer-by. The passwd
utility prompts for the new password twice in order to detect typing errors.
The new password should be at least six characters long and not purely alphabetic. Its total length should be less than _PASSWORD_LEN (cur-
rently 128 characters), although some directory systems allow longer passwords. Numbers, upper case letters, and meta characters are encour-
aged.
Once the password has been verified, passwd communicates the new password to the directory system.
-i infosystem
This option specifies where the password update should be applied. Under Mac OS X 10.5 and later, supported directory systems are:
PAM (default) Pluggable Authentication Modules.
opendirectory
A system conforming to Open Directory APIs and supporting updates (including LDAP, etc). If no -l option is specified, the
search node is used.
file The local flat-files (included for legacy configurations).
nis A remote NIS server containing the user's password.
-l location
This option causes the password to be updated in the given location of the chosen directory system.
for file,
location may be a file name (/etc/master.passwd is the default)
for nis,
location may be a NIS domainname
for opendirectory,
location may be a directory node name
for PAM,
location is not used
-u authname
This option specifies the user name to use when authenticating to the directory node.
user This optional argument specifies the user account whose password will be changed. This account's current password may be required,
even when run as the super-user, depending on the directory system.
FILES
/etc/master.passwd The user database
/etc/passwd A Version 7 format password file
/etc/passwd.XXXXXX Temporary copy of the password file
