EU Data Protection Regulations

New EU Data Protection Regulation requires you to get customer consent before using their identity data. Customers - in particular consumers - must be able to control who accesses their data.

Grean takes care of your customer's identity data and provides you with the customer control and customer consent administration you need - along with the necessary security.

Protect Against Fraud and Fakes

Your customers sign in with their own identities such as Facebook or Google - or simply with a username and password. But sometimes you still need proof of their legal identity to avoid fake identities and fraud.

Grean provides account verification/linking through easy-to-manage, hardware-backed (HSM) integration with national identity providers, such as Danish NemID and Swedish BankID.

Access and Consent Management

Whether you serve consumers or businesses, your customers should decide who gets access to their identity information. And companies must be able to manage which of their employees gets access to what.

Grean provides cloud services for authentication, onboarding, and management of user permissions. This puts control of both the process and the data back into the hands of your customers.


Reference Cases

Codan and Trygg-Hansa

Insurers Codan and Trygg-Hansa - part of RSA Scandinavia - needed better control of the look and feel of their login solution. They wanted more options for social login, and they also needed self-service onboarding and user administration for their brokers and business customers.

With Grean's cloud solution, based on Auth0 and Grean's own services, RSA Scandinavia achieved all of that while reducing infrastructure complexity and cost, and at the same time, minimizing their software development effort.

Grean now operates the entire authentication and authorization infrastructure for all of RSA’s customer-facing web applications. Also part of the mix for both personal and business users is Danish NemID and Swedish BankID for proof of identity and increased security.


Viewcare serves hospitals and municipalities with their telemedicine solution. While outside of Viewcare's core service, Viewcare found that their customers wanted various options for logging in to Viewcare's mobile and server apps. The needs for login include integration with customer Active Directory, use of national identity services such as Danish NemID, and potentially even social logins for patients.

Viewcare now partners with Grean to provide and manage the authentication, authorization, and onboarding of their customers, employees, and the patients they serve. This leaves Viewcare completely free to focus on their own apps and services, simply referring customers to Grean for all things related to login, including technical integration.
