MitID is Denmark's national eID. It's state-run, developed by Nets together with the Danish Agency for Digital Government and Finans Danmark, the organisation representing the Danish banks. It replaced NemID, which was fully switched off at the start of November 2023 once almost every Dane had migrated. It's used daily for online banking, public services such as borger.dk, skat.dk and sundhed.dk, e-commerce and signing.

People authenticate with a user ID and password plus an authenticator, usually the MitID app, which generates one-time codes, or a hardware code display or chip. MitID is recognised at eIDAS levels up to high.

MitID Erhverv is the business side of MitID. It replaced NemID medarbejdersignatur and is for companies, associations and authorities whose employees need to log in, approve and sign. It works much like personal MitID, but instead of a personal number (CPR) it verifies a company registration number (CVR). A broker is required to connect to MitID, and Scrive is a certified one.

In eID Hub, MitID is the provider dkMitID and covers both personal and business login. A completed transaction returns the user's name, date of birth and a stable user ID, with CPR and organisation details available depending on how you configure it.
