The EU’s digital transformation and the rise of trusted digital identities

The EU, like the rest of the world, is experiencing a significant digital transformation driven by emerging technologies, with citizens, businesses, and governments increasingly relying on online services.

At the centre of the shift lies digital identity, which enables secure, verifiable, and seamless online interactions.

Digital identity has also become a cornerstone of the EU’s transition toward a secure and competitive digital economy. As societies, businesses, and governments increasingly rely on online platforms, the ability for citizens to prove who they are in a reliable, secure, and user-friendly way has gained central importance.

Without trusted digital identities, essential services ranging from healthcare and education to banking and e-commerce risk fragmentation, fraud, and inefficiency.

The EU has long recognised the challenge. The first introduction of the eIDAS Regulation, on Electronic Identification, Authentication and Trust Services, in 2014, was a milestone in creating a legal framework for electronic identification and trust services across its borders.

However, it quickly became clear that further steps were necessary to improve adoption, interoperability, and user trust.

In May 2024, the updated framework, eIDAS 2 (Regulation (EU) 2024/1183), came into force.

At its heart lies the European Digital Identity Wallet, or EDIW, a tool designed to empower EU citizens with a secure, voluntary, and interoperable way to authenticate themselves and store personal credentials.

By doing so, eIDAS 2 aims to strengthen trust, security, and cross-border services, ensuring Europe builds digital sovereignty while safeguarding fundamental rights.

Lessons from eIDAS 1 and the need for a stronger digital identity framework

Back in 2014, when the first eIDAS Regulation was adopted, its purpose was to enable the mutual recognition of electronic identification and trust services across member states.

The idea was simple (and logical) yet ambitious: a citizen of one EU country should be able to use their national digital ID to access services in another, whether it is to enrol in a university abroad or open a bank account.

The original regulation created legal certainty for electronic signatures, seals, timestamps, and website authentication, helping digital transactions gain recognition equal to their paper counterparts.

For businesses and governments, it reduced bureaucracy and built trust in digital processes, both essential for sustainable development.

Despite the achievements, significant limitations emerged. Adoption rates varied widely across member states, with only a handful, such as Estonia and Denmark, achieving robust national digital ID systems.

Others lagged due to technical, political, or budgetary issues. Interoperability across borders was inconsistent, often forcing citizens and businesses to rely on paper processes.

Stakeholders and industry associations also expressed concerns about the complexity of implementation and the absence of user-friendly solutions.

The gaps highlighted the need for a new approach. As Commission President Ursula von der Leyen emphasised in 2020, ‘every time an app or website asks us to create a new digital identity or to easily log on via a big platform, we have no idea what happens to our data in reality.’

Concerns about reliance on non-European technology providers, combined with the growing importance of secure online transactions, paved the way for eIDAS 2.

The eIDAS 2 framework and the path to interoperable digital services

Regulation (EU) 2024/1183, adopted in the spring of 2024, updates the original eIDAS to reflect new technological and social realities.

Its guiding principle is technological neutrality, ensuring that no single vendor or technology dominates and allowing member states to adopt diverse solutions provided they remain interoperable.

Among its key innovations is the expansion of qualified trust services. While the original eIDAS mainly covered signatures and seals, the new regulation broadens the scope to include services such as qualified electronic archiving, ledgers, and remote signature creation devices.

The broader approach ensures that the regulation keeps pace with emerging technologies such as distributed ledgers and cloud-based security solutions.

eIDAS 2 also strengthens compliance mechanisms. Providers of trust services and digital wallets must adhere to rigorous security and operational standards, undergo audits, and demonstrate resilience against cyber threats.

In this way, the regulation not only fosters a common European market for digital identity but also reinforces Europe’s commitment to digital sovereignty and trust.

The European Digital Identity Wallet in action

The EDIW represents the most visible and user-facing element of eIDAS 2.

Available voluntarily to all EU citizens, residents, and businesses, the wallet is designed to act as a secure application on mobile devices where users can link their national ID documents, certificates, and credentials.

For citizens, the benefits are tangible. Rather than managing numerous passwords or carrying a collection of physical documents, individuals can rely on the wallet as a single, secure tool.

It allows them to prove their identity when travelling or accessing services in another country, while offering a reliable space to store and share essential credentials such as diplomas, driving licences, or health insurance cards.

In addition, it enables signing contracts with qualified electronic signatures directly from personal devices, reducing the need for paper-based processes and making everyday interactions considerably more efficient.

For businesses, the wallet promises smoother cross-border operations. For example, banks can streamline customer onboarding through secure, interoperable identification. Professional services can verify qualifications instantly.

E-commerce platforms can reduce fraud and improve compliance with ‘Know Your Customer’ requirements.

By reducing bureaucracy and offering convenience, the wallet embodies Europe’s ambition to create a truly single digital market.

Cybersecurity and privacy in the EDIW

Cybersecurity and privacy are central to the success of the wallet. On the positive side, the system enhances security through encryption, multi-factor authentication, and controlled data sharing.

Instead of exposing unnecessary information, users can share only the attributes required, for example, confirming age without disclosing a birth date.

Yet risks remain. The most pressing concern is risk aggregation. By consolidating multiple credentials in a single wallet, the consequences of a breach could be severe, leading to fraud, identity theft, or large-scale data exposure. The system, therefore, becomes an attractive target for attackers.

To address such risks, eIDAS 2 mandates safeguards. Article 45k requires providers to maintain data integrity and chronological order in electronic ledgers, while regular audits and compliance checks ensure adherence to strict standards.

Furthermore, the regulation mandates open-source software for the wallet components, enhancing transparency and trust.

The challenge is to balance security, usability, and confidence. If the wallet is overly restrictive, citizens may resist adoption. If it is too permissive, privacy could be undermined.

The European approach aims to strike the delicate balance between trust and efficiency.

Practical implications across sectors with the EDIW

The European Digital Identity Wallet has the potential to reshape multiple sectors across the EU, and its relevance is already visible in national pilot projects as well as in existing electronic identification systems.

Public services stand to benefit most immediately. Citizens will be able to submit tax declarations, apply for social benefits, or enrol in universities abroad without needing paper-based procedures.

Healthcare is another area where digital identity is of great importance, since medical records can be transferred securely across borders.

Businesses are also likely to experience greater efficiency. Banks and financial institutions will be able to streamline compliance with the ‘Know Your Customer’ and anti-money laundering rules.

In the field of e-commerce, platforms can provide seamless authentication, which will reduce fraud and enhance customer trust.

Citizens will also enjoy greater convenience in their daily lives when signing rental contracts, proving identity while travelling, or accessing utilities and other services.

National approaches to digital identity across the EU

National experiences illustrate both diversity and progress. Let’s review some examples.

Estonia has been recognised as a pioneer, having built a robust e-Identity system over two decades. Its citizens already use secure digital ID cards, mobile ID, and smart ID applications to access almost all government services online, meaning that integration with the EDIW will be relatively smooth.

Denmark has also made significant progress with its MitID solution, which replaced NemID and is now used by millions of citizens to access both public and private services with high security standards, including biometric authentication.

Germany has introduced BundID, a central portal for accessing public administration services, and has invested in enabling the use of national ID cards via NFC-based smartphones, although adoption is still limited compared to Scandinavian countries.

Italy has taken a different route by rolling out SPID, the Public Digital Identity System, which is now used by more than thirty-five million citizens to access thousands of services. The country also supports the Electronic Identity Card, known as CIE, and both solutions are being aligned with wallet requirements.

Spain has launched Cl@ve, a platform that combines permanent passwords and electronic certificates, and has joined several wallet pilot projects funded by the European Commission to test cross-border use.

France is developing its France Identité application, which allows the use of the electronic ID card for online authentication, and the project is at the centre of the national effort to meet European standards.

The Netherlands relies on DigiD, which provides access to healthcare, taxation, and education services. Although adoption is high, the system will require enhanced security features to meet the new regulations.

Greece has made significant strides in digital identity with the introduction of the Gov.gr Wallet. The mobile application allows citizens to store digital versions of their national identity card and driving licence on smartphones, giving them the same legal validity as physical documents in the country.

These varied examples reveal a mixed landscape. Countries such as Estonia and Denmark have developed advanced and widely used systems that will integrate readily with the European framework.

Others are still building broader adoption and enhancing their infrastructure. The wallet, therefore, offers an opportunity to harmonise national approaches, bridge existing gaps, and create a coherent European ecosystem.

By building on what already exists, member states can speed up adoption and deliver benefits to citizens and businesses in a consistent and trusted way.

Risks and limitations of the EDIW

Despite the promises, the rollout of the wallet faces significant challenges, several of which have already been highlighted in our analysis.

First, data privacy remains a concern. Citizens must trust that wallet providers and national authorities will not misuse or over-collect their data, especially given existing concerns about data breaches and increased surveillance across the Union. Any breach of that trust could significantly undermine adoption.

Second, Europe’s digital infrastructure remains uneven. Countries such as Estonia and Denmark (as mentioned earlier) already operate sophisticated e-ID systems, while others fall behind. Bridging the gap requires financial and technical support, as well as political will.

Third, balancing innovation with harmonisation is not easy. While technological neutrality allows for flexibility, too much divergence risks interoperability problems. The EU must carefully monitor implementation to avoid fragmentation.

Finally, there are long-term risks of over-centralisation. By placing so much reliance on a single tool, the EU may inadvertently create systemic vulnerabilities. Ensuring redundancy and diversity in digital identity solutions will be key to resilience.

Opportunities and responsibilities in the EU’s digital identity strategy

Looking forward, the success of eIDAS 2 and the wallet will depend on careful implementation and strong governance.

Opportunities abound. Scaling the wallet across sectors, from healthcare and education to transport and finance, could solidify Europe’s position as a global leader in digital identity. By extending adoption to the private sector, the EU can create a thriving ecosystem of secure, trusted services.

Yet the initiative requires continuous oversight. Cyber threats evolve rapidly, and regulatory frameworks must adapt. Ongoing audits, updates, and refinements will be necessary to keep pace. Member states will need to share best practices and coordinate closely to ensure consistent standards.

At a broader level, the wallet represents a step toward digital sovereignty. By reducing reliance on non-European identity providers and platforms, the EU strengthens its control over the digital infrastructure underpinning its economy. In doing so, it enhances both competitiveness and resilience.

The EU’s leap toward a digitally sovereign future

In conclusion, we firmly believe that the adoption of eIDAS 2 and the rollout of the European Digital Identity Wallet mark a decisive step in Europe’s digital transformation.

By providing a secure, interoperable, and user-friendly framework, the EU has created the conditions for greater trust, efficiency, and cross-border collaboration.

The benefits are clear. Citizens gain convenience and control, businesses enjoy streamlined operations, and governments enhance security and transparency.

But we have to keep in mind that challenges remain, from uneven national infrastructures to concerns over data privacy and cybersecurity.

Ultimately, eIDAS 2 is both a legal milestone and a technological experiment. Its success will depend on building and maintaining trust, ensuring inclusivity, and adapting to emerging risks.

If the EU can meet the challenges, the European Digital Identity Wallet will not only transform the daily lives of millions of its citizens but also serve as a model for digital governance worldwide.
