Klarna has been aggressive in trying to push consumers into acknowledging Klarna to pull from their accounts lately. People are used to Klarna here (Sweden), with their "pay on invoice in 14 days for no additional fee" since long, but now they're trying to leverage that into getting customers setup with their bank accounts. Of course they are not going to use this to explicitly steal from customers but still you wonder what can go wrong giving other entities this access..
