Considering everyone and their cousin has your CPR number over here, I fail to see how it could be seen as confidential. My landlord has my CPR, my company has my CPR, my network operator has my CPR, and my language school has my CPR.

Not knowing my CPR has never been a problem, but knowing it has never been an advantage. It's a unique ID as a citizen, but that's as far as it goes.

Every time I call my bank, I have to give the amount of cash available on my account for them to "authenticate" me, or tell them when was the last time I logged on to the website.
