Decentralized identity is often seen as promising – but how does it actually integrate into existing enterprise structures? In the WEB3DORS project at Fraunhofer FIT, we designed, implemented, and evaluated organizational digital identities for employees, assets, and services, sitting at the heart of a range of practical use cases. Fraunhofer served as an example organization, but the findings are transferable to organizations more broadly. Drawing on concrete project experience, this talk shares the lessons learned and their relevance for other organizations.
