NemLog-in

NemLog-in is a shared user management infrastructure for citizens, public authorities and businesses. In practice, it acts as a central entry point for anyone with MitID, MitID Erhverv or an eID from an EU/EEA country who wants to log on to digital services, such as websites or self-services, in Denmark. NemLog-in checks whether the user has the necessary rights to access the digital service they are trying to reach.

NemLog-in was originally launched in 2008. The current version is the third generation and has been in operation since 2023. More than 500 digital services now use NemLog-in, handling around 35 million transactions a month.

NemLog-in is a MitID broker. A broker is a trusted third party that passes on user authentications to other organisations' services by issuing its own authentication tokens, which those services trust. Service providers — public authorities or businesses that own a self-service with a login function — can use a MitID broker so that their digital services can be equipped with access control by using MitID or MitID Erhverv.

When you as a user visit a digital service, such as a self-service or website, that uses NemLog-in, you will be redirected to a common log-on page shared by all digital services using NemLog-in. After logging in, you will automatically be returned to the digital service you were about to access.

NemLog-in offers a Single Sign-On (SSO) solution for digital services that involve the exercise of public authority. This means you only need to identify yourself once, even when accessing more than one public-sector digital service.
