MitID is Denmark's national digital identity system. Citizens use it to prove who they are online, for example when logging in to the citizen portal borger.dk or to online banking. Public authorities and private providers accept it as a login method, which makes it the main entry point to many Danish digital services. In the MitID partnership, the Danish Agency for Digital Government (Digitaliseringsstyrelsen) represents the state, the regions and the municipalities, and the Danish banks take part through a subsidiary of Finans Danmark.
The development and operation of the system were awarded to Nets DanID A/S in a 2019 tender. Digitaliseringsstyrelsen is now preparing a new tender for operation, maintenance and support, so the operator could change. MitID serves Danish citizens and businesses, and MitID Erhverv is the variant for Danish companies and associations. A European organisation outside Denmark mainly meets MitID as a login option offered by Danish services.
