Strong Authentication with German eID Card reaches general public with Nextcloud and free https://eID.Services

[Michelau, 23 June 2021] ecsec GmbH developed the “eID-Login” App for Nextcloud on behalf of the Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik, BSI) and published it now under an Open Source License. This is the first time the German eID is integrated with a mainstream platform. Thanks to the SkIDentity service, which is provided without fee for the project, the German eID card can now be used free of charge for strong authentication in Nextcloud.

German eID Card can now be used in Nextcloud for strong authentication

The German eID Card (“Personalausweis”), which has been notified at the highest possible level of assurance (“high”) in accordance with the eIDAS-Regulation, can be used by all citizens for electronic identification (eID) and for strong pseudonymous authentication on the Internet. Until now, this has been used in a range of special applications mostly in the German government sector. With the “eID-Login” App for Nextcloud developed by ecsec GmbH on behalf of the Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik, BSI), it is now possible to use the German eID Card in the popular cloud solution for strong authentication.

Security by Design and Open Source guarantee highest level of trustworthiness

The early and consequent consideration of relevant security aspects according to the „Security by Design“ principle and the publication of the "eID-Login" App for Nextcloud as Open Source ensure that a very high level of trustworthiness is achieved. "It is great to see Nextcloud as the first mainstream platform with support for the German eID Card for strong authentication and identification," adds Frank Karlitschek, founder and managing director of Nextcloud GmbH. “We look forward to many users of this innovative authentication technology.”

Cooperation between BSI and ecsec GmbH enables free https://eID.Services

So that the German eID Card can be used immediately and free of charge for strong authentication in Nextcloud, the SkIDentity service, which has won multiple international awards, is also provided for strong authentication free of charge as part of the joint project. In addition to the free authentication service, the eID experts at ecsec GmbH also offer additional support services for hosting providers and application developers (see https://eID.Services) so that the "eID-Login" functionality can easily be integrated and used in other Open Source applications as well. "The provision of the eID-Login App for Nextcloud as Open Source is to be understood as a prelude and invitation to the community," adds Tina Hühnlein, founder and managing director of ecsec GmbH. "We are very confident that there will soon be more web applications with eID-Login."
