When you need to know the legal identity of your Danish users, your choice is NemID offered by the Danish Government. NemID exists in both a version private citizens and one for employees of an organization.
The NemID technology by itself is proprietary and takes quite a bit of work to understand and integrate, but through the Criipto Verify service you may avoid the integration trouble.
Below is an outline of the steps to get ready to accept Danish NemID logins, but you may also view a short screen cast at Criipto's website.
Process to use Swedish BankID in Production
While the technical integration is simple, to use Danish NemID in production you will have to go through a formal process to register and obtain the necessary certificate to identify yourself to your users. This proces must be completed with the Danish NemID operator, Nets. More on this process can be found once you sign into the Criipto Verify service, and with the help of Criipto.
1. Create an account with Criipto Verify
Go to criipto.com/verify and click the sign-up button.
Once registered you will be asked to create your tenant.
2. Create an Application to point to Auth0
In Criipto Verify go to the APPLICATIONS tab and create a new application by clicking the with Auth0 button. Give it a meaningful name, select the domain and remember to select the DK NemID.
Click Save to open the next dialog
3. Name the connection (prefix) as it will appear in Auth0
If you do not run off the public Auth0 service, enter the DNS name of the login tenant. Otherwise just leave the Auth0 tenant field as is.
Secondly enter a name to be used as the prefix for the connections created in Auth0.
4. Create new connections in Auth0
If you are not already logged in to Auth0 in this session, you will be prompted to do so in the popup window.
Once logged in you must grant Criipto Verify consent to create connections and read the details of your applications.
Click the check mark in the green area at the bottom to allow Criipto Verify to set up the connections.
5. Verify the connections
Go to the Connections > Enterprise section and open the ADFS connections to see the connections for Danish NemID created from the previous steps.
Remember to enable at least one application before clicking the Try button! For more on test users see the documentation on Criipto Verify.
6. Create your test users
With the above setup you will be ready to start testing. But first you must create one or more test users or get some from Criipto. See more in the documentation in your Criipto Verify tenant.
7. Enable production use
To start accepting real NemID logins from real legal persons, you must first enter into a formal agreement with Nets, the company providing the service under contract from the Danish Government. More on this here (in Danish): www.nets.eu/dk-da/l%C3%B8sninger/nemid/nemid-tjenesteudbyder/Pages/bestil.aspx
Once this agreement is in place you will receive a certificate to upload to Criipto Verify. Go to the IDENTITY SERVICES tab and open the DK NemID section. This is where you will upload your organization's BankID certificate and provide the rest of the needed information.
