Abstract: In order to break the fragmentation of digital identity, remove the barriers for citizens and enterprises to use their national digital identity for cross-border access to online services, and promote the formation of a single digital market in the EU, the EU has introduced eIDAS regulations at the legal level to clarify the responsibilities of all parties in digital identity, unify the standards of digital identity assurance level, and enforce mutual recognition among digital identities of Member States, and build The interconnection infrastructure of eIDas network, such as national nodes, actively guides the innovation practice related to digital identity through financial support and other means, strengthens the cooperation between the state and all sectors of society, and achieves good results. At the same time, the EU has introduced norms such as the level of digital identity assurance and raised them to legal requirements. By investing in a series of digital identity research and infrastructure projects, the EU has promoted the actual mutual recognition of digital identities, reduced the relevant economic and social costs, and strongly supported the development of the local digital economy. Its experience and practice are worth learning. This paper focuses on the EU's work in the field of digital identity management, hoping to provide some reference for China's digital identity governance.
