NOTE: The CEF Digital Portal is the home of the CEF building blocks (eID, eDeliveryeInvoicing, eSignature and eTranslation). It is the one-stop-shop for information about the building blocks. The portal provides access to tools, services and software that can be used in any European project to facilitate the delivery of digital public services across borders.


Special announcement for eID users: starting with the eIDAS-node v1.1, which was released on 30/06/ 2016, eID will release all future versions of the eIDAS sample implementation on the CEF Digital Portal, issues with this and all future releases will be managed via the CEF Digital Portal.

Starting with eIDAS-node v1.1, eID will release all future versions of the eIDAS sample implementation and manage issues via the CEF Digital Portal.


The electronic identity (eID) building block helps public administrations and private online service providers to easily extend the use of their online services to citizens from other EU Member States. It allows cross-border authentication, in a secure, reliable and trusted way, by making existing national electronic identification systems interoperable.

Once this building block is deployed in a Member State, the mutual recognition of national eIDs becomes possible between participating Member States, in line with the eIDAS (electronic Identification and Signature) legal framework and with the privacy requirements of all the participating countries. Mutual recognition of national eIDs allows citizens of one Member State to access online services provided by public and private organisations from other participating EU Member States, using their own national eID.

The eID solution provides a strong technical foundation for secure electronic interaction across borders and sectors.


The CEF eID solution is based on the results of the Secure idenTity acrOss boRders linKed (STORK) project, co-funded under the ICT Policy Support Programme of the Competitiveness and Innovation Framework Programme (CIP). For more information about this software, please refer to the STORK page.   The solution is primarily based on the following soſtware components:
  • A package for Member States to become eIDAS enabled. This package includes the necessary modules to communicate with other eIDAS enabled Member States in a centralised or distributed fashion.
  • Additional tools for setting up a demo environment for testing purposes.
  • 21 September 2015: release of preview of the CEF eID Building Block (version 0.9) to help accelerate the implementation of the eIDAS Regulation. The main features are:
    • Support to eIDAS message format (eIDAS technical specification) and extension of eIDAS metadata (eIDAS Technical Specification);
    • Security improvements;
    • Extension of the sample applications (Service Provider, Identify Provider and Attribute Provider) to provide a sample of use of the eIDAS Regulation features;
    • An additional feature selector enforcing eIDAS Regulation compliance.
  • 30 September 2015: the STORK project ends
  • December 2015 (indicative timing): release of the CEF eID Building Block (version 1.0). The main features are:
    • Improved modularity;
    • Code cleaned;
    • New look and feel.
  • 2016-2018: two major releases will be made per year and minor intermediary releases based on the needs of the eID community.
  • 18 September 2018: Mandatory eID recognition.

Future plans

  • eIDAS-compliant release planned for September 2015
