Hey!

Your question seems a bit incomplete. If you could provide the details regarding name of the exam and other such information, then it would be useful and more accurate answer can be provided in order to solve your query. It is because it's not necessary that every procedure of getting the admit card or filling the form is same. In general case scenario, what happens is that one fills the registeration form and the admit card is provided about 1 week before the exam. But since you have mentioned requiring of password for the purpose, then it is definite that it might have a different procedure. You may write the required details in the comment section or you may post your question with adequate details.
