Misconception? The Nordic Passport Union is still quite valid. Quoted from Wikipedia: "Within the Nordic area, any Nordic identity documentation (e.g. a driving license) is valid as proof of identity for Nordic citizens because of the Nordic Passport Union, while a national identity card or a passport is can be required in other Schengen countries" https://en.wikipedia.org/wiki/Nordic_Passport_Union https://en.wikipedia.org/wiki/Nordic_Passport_Union In other words, you need to be able to identify yourself, but not necessarily with a national ID or a passport as you would when entering other parts of the Schengen area. The border controls between Denmark and Sweden are a temporary suspension of those rules but it only concerns people crossing the border at those points -- not people who who are already in the country or people who cross the borders at other locations, like say, the Finnish/Swedish border.
