The digitalization has become increasingly central in today’s society and digital identities are one of the tangible changes that has quickly become integrated into our society. However, increased integration in societies also creates new challenges and responsibilities. The European Union (EU) has recognized this need and implemented the eIDAS regulation (electronic Identification, Authentication, and trust services). In the regulation, a digital identity wallet is also proposed. The aim of the wallet is for users to store and manage their digital identities and credentials such as driver’s licenses, university degrees, and similar documents. With this development and introduction of a digital identity wallet, questions about trust become relevant. Trust in digital identities is crucial to ensure communication and data management, as well as to get users to use the services.  The purpose of this study has been to examine aspects of trust related to the EU digital identity wallet and explore key components and actors within the wallet’s eco-system. The work has been limited to focusing on the electronic identification component of eIDAS. Furthermore, data has been collected from interviews with experts in the field from Sweden and the Netherlands. The theory used is definitions and concepts on what trust entails, as well as two frameworks explaining factors important to initially trust a system, and explaining the relationship between usability, privacy, and security.  The results conclude that users prioritize usability over security and privacy, and that an application that is simple and practical also are important features of a digital identity wallet. It also emerged that it is important for users that safety nets are built into the wallet. Furthermore, users, the EU, and the respective member states were identified as fundamental actors of the ecosystem. It was emphasized that the wallet is complex and that there are many challenges and opportunities ahead to build a trustworthy wallet.

This thesis deals with digital identity wallets as digital identification means, through a legal and technical perspective, within the field of legal informatics. The 3rd of July 2021 the European Commission presented a proposal for a regulation of the European Parliament and of the Council amending Regulation (EU) No 910/2014 as regards establishing a framework for a European Digital identity, also known as the eIDAS II-regulation. The eIDAS II-regulation is at this moment being negotiated on EU-level and has not yet been adopted. In the eIDAS II-regulation the digital identity wallets were presented. These wallets en-able citizens and other residents to authenticate, and share electronic documents and identification data, with a relying party. The purpose of the digital identity wallets is to create a harmonized identification solution that will function within all member states of the EU. The thesis will concentrate on the relationship between the legal aspects of the eIDAS II-regulation and the technical solutions presented in the regulation. The eIDAS II-regulation covers a vast variety of legal and technical solutions, however the thesis will only focus on the electronic identification, authentication, and the sharing of electronic documents through the wallet. Furthermore, the thesis will analyse which data can be stored in the wallet according to the eIDAS II-regulation and what legal and technical solutions are proposed to enable shar-ing, and controlling the accuracy, of the data. The relationship between eIDAS II-regulation and GDPR will be discussed and analysed in the end of the thesis. This discussion gives the reader an understanding of how the regulations will integrate with each other and how eIDAS II-regulation is affected by the GDPR. The conclusion of the thesis is that the eIDAS II-regulation, thus the digital identity wallets, is a step in the right direction to create a harmonized regulation for digital identities, however there are certain legal problems that should be ad-dressed to make the digital identity wallets a secure and user-friendly solution. These legal problems with the digital identity wallets could be solved with the right technical specifications. Some of these technical specifications will be pre-sented and discussed in the thesis.
