Login Service

Text of the declaration of consent

The page accessed here is the Identity Provider (IdP) of the GEOMAR Helmholtz Centre for Ocean Research. The IdP is used for secure login to services, so-called Service Providers (SP), which are available via DFN-AAI. The IdP is connected to the GEOMAR user directory.

The authentication and authorization infrastructure DFN-AAI is managed by the DFN-Verein. It creates the necessary relationship of trust and the organizational-technical framework for the exchange of user information between institutions (IdP) and service providers (SP-operators) in the DFN-AAI.

As part of the registration process, the IdP first authenticates the users. This is usually done by entering the user ID and a password. The verification of your login data is always done at the IdP of GEOMAR. These login data are not transmitted to a SP. Subsequently, the information required to use the SP (so-called attributes) is transferred to the SP in question. These can be for example the name, the e-mail address or the group membership within the institution (student, employee, ...).

In order to implement the principle of data minimization, many SPs request only SP-specific, persistent pseudonymous identifiers instead of clear names. In order to implement this, these identifiers are generated and permanently stored by the IdP during the registration process. By activating the checkbox below this text, you consent to the storage of the associated information by the IdP. You can revoke this consent at any time by sending an e-mail to By revoking your consent, the legality of the processing that took place on the basis of your consent until the revocation is not affected.

Further information on data protection can be found in the privacy policy.
