Passwords are stored in /etc/shadow for security reasons:
-rw-r--r-- /etc/passwd
-rw------- /etc/shadow
>From shadow(5) manpage:
If the password field contains some string that is not valid result of
crypt(3), for instance ! or *, the user will not be able to use a unix
password to log in, subject to pam(7).
