Since July 3, 2017, the source code of AusweisApp2 is available on the online platform Github (for software development projects with version management - www.github.com). Under the EUPL license, users can obtain the original source code, copy it, develop it further, program optimizations and make it available to the community again.
The federal government has changed the license of AusweisApp2 to allow, for example, the provision of the eID client for operating systems that are not officially supported. It is now also possible to use it at citizen terminals and to deeply integrate the eID function into own applications. Suitable changes from the community can then be adopted for official further development and incorporated into the certified AusweisApp2 provided by the federal government.
