It asks for password in the screen and wait for user input to enter the password. ... Is it possible to pass the password through script?

It is certainly possible to have your script interact with another application as if it were a user. I think this would be done with a module like Expect, but I personally have no experience with this module or with this sort of application-application interaction. Maybe open a fresh thread in SoPW with a title like "How Can My Script Submit a Password when Prompted by an Application?", or use Super Search with similar search terms.
