Klarna checkout without registration?

How do I make the klarna checkout without having to register as user?

As far as I know the whole meaning of klarna is that people wouldn't need to register and make fast payments..

is there any specific page i need to include in the checkout.inc.php ?

Would you like to substitute the LiteCart Checkout with Klarna Checkout instead? Meaning the orders would not be stored in LiteCart at all.
