Many methods are there.

(1)  Pass the password as a command line argument (insecure method)
(2)  Pass the name of a password file on the command line (not fool-proof but better than the previous one)
(3)  Give the execute permission only to the user whom you want to validate. That way the OS would validate him anyway when he tries logging into the system
