It would work in bash, but I guess you are using plain, old sh.
If it's just a simple solution you want, the stty -echo option from felipe.vinturin is fine.

pwauth
PWAUTH(8) System Manager's Manual PWAUTH(8)
NAME
pwauth - authenticator for mod_authnz_external and the Apache HTTP Daemon
SYNOPSIS
pwauth
DESCRIPTION
Pwauth is an authenticator designed to be used with mod_auth_external or mod_authnz_external and the Apache HTTP Daemon to support reason-
ably secure web authentication out of the system password database on most versions of Unix. Particulary - secure authentication against
PAM.
The simplest test pwauth is to start a root shell and just run pwauth. It will attempt to read the login and password from standard input,
so type a login name, hit return, then type a password, and hit return (the password will echo on your screen). The check the status code
that was returned (in csh: "echo $status" in sh: "echo $?").
If the login/password were correct you should get a zero status code. If not, you will get some other value. See below the list of status
codes to find the meaning of the various values returned. Any values 50 or greater indicate a configuration error.
STATUS CODES
0 STATUS_OK
Login OK.
1 STATUS_UNKNOWN
Nonexistant login or (for some configurations) incorrect password.
2 STATUS_INVALID
Incorrect password (for some configurations).
3 STATUS_BLOCKED
Uid number is below MIN_UNIX_UID value configured in config.h.
4 STATUS_EXPIRED
Login ID has expired.
5 STATUS_PW_EXPIRED
Login's password has expired.
6 SSTATUS_NOLOGIN
Logins to system have been turned off (usually by /etc/nologin file).
7 STATUS_MANYFAILES
Limit on number of bad logins exceeded.
50 STATUS_INT_USER
pwauth was invoked by a uid not on the SERVER_UIDS list. If you get this error code, you probably have SERVER_UIDS set incorrectly
in pwauth's config.h file.
51 STATUS_INT_ARGS
pwauth was not given a login & password to check. The means the passing of data from mod_auth_external to pwauth is messed up. Most
likely one is trying to pass data via environment variables, while the other is trying to pass data via a pipe.
52 STATUS_INT_ERR
one of several rare and unlikely internal errors occurred. You'll have to read the source code to figure these out.
53 STATUS_INT_NOROOT
pwauth was not able to read the password database. Usually this means it is not running as root. (PAM and login.conf configurations
will return 1 in this case.)
