This is from my manual page on 'passwd'. Yours may not have this option. I believe some versions of passwd are intentionally written so that the password must be entered from the keyboard.
Code:
$ man passwd
...
--stdin
This option is used to indicate that passwd should read the new password
from standard input, which can be a pipe.
I want to write a script which will automatically take password
sequentially from a file after every 10 days.
i.e the passwd command should be executed automatically every 10 days and it should take the input from the password file sequentially.

pwconv
pwconv(1M) System Administration Commands pwconv(1M)NAME
pwconv - installs and updates /etc/shadow with information from /etc/passwd
SYNOPSIS
pwconv
DESCRIPTION
The pwconv command creates and updates /etc/shadow with information from /etc/passwd.
pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is
already in /etc/shadow and should not be modified.
If the /etc/shadow file does not exist, this command will create /etc/shadow with information from /etc/passwd. The command populates
/etc/shadow with the user's login name, password, and password aging information. If password aging information does not exist in
/etc/passwd for a given user, none will be added to /etc/shadow. However, the last changed information will always be updated.
If the /etc/shadow file does exist, the following tasks will be performed:
Entries that are in the /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file.
Entries that are in the /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow.
Password attributes (for example, password and aging information) that exist in an /etc/passwd entry will be moved to the corre-
sponding entry in /etc/shadow.
The pwconv command can only be used by the super-user.
FILES
/etc/opasswd
