Helmholtz AAI

This is the technical and administrative documentation on Helmholtz AAI, built and maintained by HIFIS.


For a high-level representation, have a look at the Helmholtz AAI Homepage on

Here we describe all you need to know about joining as a user, registering a Virtual Organisation (VO), managing groups in VOs, registering a service, joining as an identity provider, or using the AAI capabilities to authorise users and user groups for fine-grained access to your service(s).

We further describe our goals, technology, and policies, and give further organisational information (see menu).


The goal of Helmholtz AAI is to enable stakeholders with a Helmholtz background to accomplish several tasks:

  • Enable the participating Helmholtz Centres to provide services to well defined sets of federated users, based on solid authentication and authorisation.
  • Enable Principal Investigators (VO Managers) at Helmholtz Centres to allocate resources on behalf of their group (VO) and to manage the authorisation for the members of their VOs.
  • Enable global researchers to use services provided by Helmholtz Centres - given they are properly authorised and their identity is adequately understood.
  • Align with European activities that focus around the European Open Science Cloud (EOSC).
