Whether you already have signed a service provider agreement with DanID, or just considering becoming NemID service provider, DanID need some information about your company in order to give you access to NemID test environment.

It is a prerequisite for accessing NemID test environment that you have a test company signature (test VOCES), since a production company signature can not be used in the test environment. If you already have a test-Corporate Signature, you can use it, alternatively you may order one at DanID.

Friendly Name

The Friendly Name field will be displayed in NemID applet to identify the service provider that the user tries to access. The user would for example be able to read, "You are now by logging on Acme Corp" where Acme Corp in this case constitutes Friendly name. Note: DanID make a concrete assessment of whether Friendly name is correct.

CVR/UID from the test VOCES certificate to test system

Information about CVR/UID in the test VOCES certificate may be found in the certificate details. It contains the field "Subject", under properties, serial number (serialNumber) and the value for CVR/UID can be read here.

Service provider package

Once agreements are signed, you must fill out a form for establishing service provider so that you receive access to the right systems in DanID. You can find this form together with your service provider package, which also provides information and software for use in the testing phase.

Read more about establishing agreement and service provider package.

Creating test users

DanID have developed a tool that enables service providers themselves to create the test users they want. With this tool you can:

  • Create a new test user with key card and temporary password
  • See transaction logs for a specific test user
  • The tool automatically ensures that new key cards are granted when there are only 20 keys left on the key card

For more information about the creation of test users, click the "Creating test users" tab at the top of this page.
