The sudo tool is designed to give you the choice. It is probably the best way.
Incidentally, you should not really try to force the password in like this. If you have a process to run that is automated, i.e. you don't fire it off as a real person on the command line, then you should really run it as a non-personal account. You can then give that account the sudo privilege to not require a password.
The problem is that if you script this, then anyone able to read your script will know the account password. Additionally, good practice would have you changing the passwords regularly and that might require editing every script each time.
How far have you got with this now?
Kind regards,
Robin

passwd
PASSWD(5) File formats PASSWD(5)
NAME
passwd - password file
DESCRIPTION
Passwd is a text file, that contains a list of the system's accounts, giving for each account some useful information like user ID, group
ID, home directory, shell, etc. Often, it also contains the encrypted passwords for each account. It should have general read permission
(many utilities, like ls(1) use it to map user IDs to user names), but write access only for the superuser.
In the good old days there was no great problem with this general read permission. Everybody could read the encrypted passwords, but the
hardware was too slow to crack a well-chosen password, and moreover, the basic assumption used to be that of a friendly user-community.
These days many people run some version of the shadow password suite, where /etc/passwd has *'s instead of encrypted passwords, and the
encrypted passwords are in /etc/shadow which is readable by the superuser only.
Regardless of whether shadow passwords are used, many sysadmins use a star in the encrypted password field to make sure that this user can
not authenticate him- or herself using a password. (But see the Notes below.)
If you create a new login, first put a star in the password field, then use passwd(1) to set it.
There is one entry per line, and each line has the format:
account:password:UID:GID:GECOS:directory:shell
The field descriptions are:
account the name of the user on the system. It should not contain capital letters.
password the encrypted user password or a star.
UID the numerical user ID.
GID the numerical primary group ID for this user.
GECOS This field is optional and only used for informational purposes. Usually, it contains the full user name. GECOS means
General Electric Comprehensive Operating System, which has been renamed to GCOS when GE's large systems division was sold
to Honeywell. Dennis Ritchie has reported: "Sometimes we sent printer output or batch jobs to the GCOS machine. The gcos
field in the password file was a place to stash the information for the $IDENTcard. Not elegant."
directory the user's $HOME directory.
shell the program to run at login (if empty, use /bin/sh). If set to a non-existing executable, the user will be unable to
login through login(1).
NOTE
If you want to create user groups, their GIDs must be equal and there must be an entry in /etc/group, or no group will exist.
If the encrypted password is set to a star, the user will be unable to login using login(1), but may still login using rlogin(1), run
existing processes and initiate new ones through rsh(1), cron(1), at(1), or mail filters, etc. Trying to lock an account by simply chang-
ing the shell field yields the same result and additionally allows the use of su(1).
