Understanding the European Digital Identity Wallet (EUDI Wallet)

European Digital Identity Wallet

By the end of 2026, every EU member state must make a certified European Digital Identity Wallet available to its citizens, residents, and businesses. This personal digital wallet is a secure and private tool designed for individuals and organizations to prove their identities, share data, and sign documents across European Union member states. The European Digital Identity Regulation (EU) 2024/1183, adopted on 20 May 2024, mandates that every Member State must provide at least one version of the wallet, and these must adhere to common specifications to ensure interoperability and cross-border recognition as part of the EU’s digital identity initiative. This is a landmark shift in how more than 450 million Europeans will verify their identity — both online and offline. The eIDAS 2.0 Regulation introduces a unified framework for digital identity that will affect both the public and private sectors.

Key Takeaways

• The EUDI Wallet will become the digital identity standard across the EU by end of 2026, as required by eIDAS 2.0.
• The digital wallet will allow citizens and businesses to log in, sign documents, and share attributes (such as age or a driving licence) across the entire European Union. It is designed to enable users to securely verify their identity and interact seamlessly with both public and private sector services through secure, interoperable mechanisms.
• The wallet gives users complete control over their data, enabling them to choose what information to share and with whom, and is specifically designed to prevent users from unnecessarily sharing personal data when accessing services, thereby enhancing privacy.
• EUDI enforces interoperability of digital services across the EU, bringing in banks, fintechs, e-commerce providers, and Very Large Online Platforms (VLOPs).

Overview of the European Digital Identity Wallet (EUDI Wallet)

The EUDI Wallet differs from existing solutions such as bank-based IDs or national digital ID cards through its shared Architecture and Reference Framework (ARF), which ensures cross-border acceptance. In Poland, integration with the mObywatel app is planned, allowing users to access the European identity wallet without installing a separate application.

The Importance of Digital Identity in Europe

The EU’s digital strategy and the Digital Single Market require trusted, interoperable identification. Existing disparities between countries have long hindered cross-border mobility and access to public services.

In the public sector, digital identity supports:

• e-government and public services,
• e-health and electronic prescriptions
• business registers
• public procurement

For the private sector, the European digital identity framework means streamlined processes across banking, fintech, insurance, and telecommunications. The broader regulatory context is reinforced by eIDAS, the AML package, PSD2/PSD3, DORA, and NIS2 — all of which require robust identity verification.

Key Features of the European Digital Identity Wallet

The European Digital Identity Wallet stores two types of data:

• Person Identification Data (PID) – identity data such as name, address, date of birth, and nationality
• Electronic Attestations of Attributes (EAA) – attribute credentials such as qualifications, driving licences, and diplomas

Function	Description
Strong authentication	Logging in to public and commercial services
Electronic signature	Legally binding across the EU
Selective disclosure	Proving age without revealing date of birth
Offline mode	Roadside checks without internet access (ISO/IEC 18013-5)

Interoperability is enabled through standards such as OpenID for Verifiable Credentials (OIDC4VCI, OIDC4VP) and W3C VC 2.0, meaning the wallet can be used in any EU country.

Enhanced Security in the EUDI Wallet

Security and privacy protection are core foundations of the project, following privacy-by-design and security-by-design principles. The EUDI Wallet must comply with eIDAS 2.0, NIS2, the Cyber Resilience Act, and future EUCC certification schemes.

Key Security Standards Include:

• Modern cryptography and zero-knowledge proofs
• Secure hardware environments (Secure Enclave, HSM)
• Multi-factor authentication
• Auditable logging of all operations

 

User Control Over Data and Privacy

One of the main motivations behind EUDI is giving citizens control over their own data. Users decide when, with whom, and which attributes they share, in line with the concept of self-sovereign identity.

Selective disclosure mechanisms make it possible to:

• Prove legal age without revealing date of birth
• Verify student status without disclosing full personal details
• Confirm professional qualifications without sharing an address

PIDs are issued by trusted public authorities, while EAAs may be issued by universities, professional bodies, or government offices. Processing must comply with GDPR, including transparency, data minimisation, and the right to erasure.

Wallet Interoperability Across EU Services

The Architecture and Reference Framework (ARF) defines common components, interfaces, and trust levels. Member States must ensure their national implementations meet these requirements.

Thanks to shared PID and EAA formats, any EU citizen can use a wallet issued in one country to authenticate in another. If recognised by the relying party, the process is immediate and seamless.

Acceptance Obligations:

• Public services – immediately upon implementation
• VLOPs (under the Digital Services Act) – mandatory acceptance
• Private sector (banks, telecoms) – deadline around 2027

Typical use cases include opening a bank account abroad, enrolling at a foreign university, renting accommodation, or activating telecom services.

Impact on Citizens and Businesses

EUDI transforms both user experience and business processes. Citizens gain one unified identity tool for use across the EU instead of managing multiple local accounts.

For regulated businesses (banks, payment institutions, insurers, crypto providers, telecoms), this means:

• Simplified customer onboarding
• New technical and legal obligations
• Need to integrate IAM/CRM systems with EUDI

 

Benefits for Individual Users

The “one app, many uses” experience means:

• Fast login to banks, universities, and e-commerce platforms without repeated registration
• Secure data sharing without sending scans of identity documents
• Proving age, renting a car, signing contracts — all from one app

In addition, EUDI simplifies cross-border mobility by making access to public and private services across the EU easier and less bureaucratic.

Benefits for Businesses and Institutions

The European Digital Identity Wallet is a catalyst for digital transformation:

Benefit	Business impact
Reduced KYC costs	Less manual document verification
Compliance	Easier fulfilment of AML, PSD3, eIDAS requirements
Fraud reduction	Stronger authentication, liveness checks
New models	Remote contract signing across the EU

The Future of EUDI and Digital Identity in Europe

The launch of EUDI by 2026 is only the beginning of an evolving ecosystem. EU Member States may expand integration into healthcare, education, and professional registers. Pilot projects such as POTENTIAL and APTITUDE, along with national rollouts such as integration with mObywatel, are testing new features.

Technology trends include AI-powered biometric verification, W3C VC 2.0 standards, and offline/NFC scenarios. Providers will become key partners for institutions combining EUDI with modern identity processes — initially on a voluntary basis for early adopters, and later as a regulatory requirement.

A European Commission recommendation calling for rapid implementation highlights the strategic importance of European digital identity for Europe’s competitiveness.

FAQ – Frequently Asked Questions About the European Digital Identity Wallet

 

When will the European Digital Identity Wallet be available to citizens?

The eIDAS 2.0 Regulation states that Member States should provide at least one certified identity wallet by the end of 2026. In Poland, plans for a pilot launch within the mObywatel app include testing through the POTENTIAL and APTITUDE projects, with full rollout planned for late 2026.

Will using the EUDI Wallet be mandatory?

The Regulation requires states to provide the wallet, but use by citizens remains voluntary. In practice, many services are expected to offer EUDI as the most convenient login method. All Member States will be required to recognise and accept wallets issued by other countries.

What documents and data can be stored in the EUDI Wallet?

The foundation consists of PID identity data and EAA credentials. Examples include driving licences, university diplomas, professional qualifications, student status, business licences, and proof of address. Both private sector organisations and public institutions will be able to issue various credentials within the wallet infrastructure.

How can companies prepare technically for EUDI integration?

Companies should monitor eIDAS 2.0 implementing acts and ARF standards. Early preparation should include updating KYC/AML processes, adapting login systems, and selecting technology partners.

Will the European wallet replace national apps such as mObywatel?

In most countries, EUDI will be integrated into existing applications rather than replacing them. Users will continue using their national app while gaining cross-border functionality throughout the European Union. European standards will benefit everyone — both citizens and businesses operating in the Digital Single Market.
