But back to my point - if you for whatever reason get compromised to such a degree that other people can sign off things with your BankID, you're basically completely fucked. At least for probably 99.99% of the cases.
This is because the law recognizes that sign-off as if you did it. And if some other did it, you've breached the ToS - which more or less states that you, and you only, can know the password, and it is your responsibility that said password is hidden / unavailable to others. Your signature and confirmation, your loan.
The most common victims of these cases are spouses and close family members.
But again, these things do differ from country to country.
Consumers in Scandinavia are not responsible when scammed unless they've acted with grave misjudgment or ill intent.
There was even a case in the high court to cement this right in Sweden this summer specifically for BankID.

Consider the case where I have a small checking account in which I deposit my child's allowance, the child discovers that this account has $10,000 in it for some reason, and, like a child, goes on a spending spree. Is my child responsible for exercising some measure of restraint with this money? They are, in the eyes of the bank, authorized to access this money for their own use, but suddenly you think that I am obligated to return thousands of dollars that my child spent on minecraft skins or something because the lender wants to lower the friction for loan applications?
The lender should be generally SOL.
