The European Union’s eIDAS 2.0 regulation is transforming digital identity by introducing the European Digital Identity Wallet (EUDI Wallet) — a secure, standardized way for citizens and businesses to verify identity across borders. By combining advanced encryption, blockchain, and privacy-by-design principles, the EUDI Wallet makes compliance with eIDAS 2.0 easier for governments, enterprises, and service providers while improving user trust.
For organizations, adopting EUDI Wallet technology means meeting stricter security, interoperability, and data-handling standards. For individuals, it offers more control over personal information and seamless access to both public and private services throughout the EU.
What Is eIDAS 2.0?
Introduced in 2014, the original eIDAS regulation established a framework for electronic identification and trust services across EU member states. However, adoption was limited due to:
Low usage of national eID systems
Fragmented solutions without consistent cross-border recognition
Rising concerns over privacy and data security
eIDAS 2.0, adopted in 2021 and finalized in 2024, expands the framework by mandating EUDI Wallets for all EU member states. These wallets:
Securely store and manage verified credentials such as ID cards, licenses, health records, and professional certificates.
Enable access to online services across EU borders without duplicated registrations.
Support legally recognized digital signatures and authentication methods.
Why the Update Was Necessary
1. Cross-Border Interoperability
Under eIDAS 1.0, recognition across member states was inconsistent. eIDAS 2.0 fixes this by requiring a standardized identity wallet format recognized EU-wide.
2. Privacy and Data Minimization
The new framework ensures selective disclosure, enabling users to prove eligibility or identity without sharing unnecessary personal details.
3. Adoption of New Technologies
By integrating blockchain, biometrics, and mobile wallets, eIDAS 2.0 future-proofs the EU identity framework against evolving security and usability standards.
4. Stronger Trust in Digital Interactions
EUDI Wallets provide cryptographically verified credentials, reducing fraud risks and building confidence in online transactions.
What Is the EUDI Wallet?
The European Digital Identity Wallet is a government-approved mobile application enabling citizens and businesses to:
Store and use secure, verified credentials.
Access public and private services seamlessly across borders.
Sign and verify digital contracts with EU-wide legal validity.
Core Features
Unified Digital Identity: Works across all EU states, replacing disparate systems.
Cross-Border Authentication: Enables secure service access in any member state.
Privacy by Design: Grants users full control over the data they share.
Secure Data Sharing: Uses end-to-end encryption and strong authentication.
Digital Signature Support: Integrates qualified electronic signatures recognized throughout the EU.
How EUDI Wallets Work
1. Credential Issuance
Trusted authorities issue digital credentials, cryptographically signed and stored securely in the user’s wallet.
2. Secure Storage
Credentials are kept in encrypted form, accessible only via biometric authentication or PIN.
3. Authentication & Verification
Service providers request identity confirmation, which is verified using cryptographic proofs without exposing full personal records.
4. Cross-Border Recognition
Standardized credentials ensure interoperability and legal recognition in all EU countries.
5. Selective Disclosure
Users can verify attributes (e.g., “over 18”) without revealing sensitive personal details.
How EUDI Wallets Support eIDAS 2.0 Compliance
1. Compliance Through Standardization
Wallets follow EU-approved frameworks for issuance, storage, and verification, ensuring consistent recognition across member states.
2. Advanced Authentication
Multi-factor methods—biometrics, PINs, and cryptographic keys—meet stringent eIDAS 2.0 security requirements.
3. Privacy-Centric Management
Selective disclosure prevents oversharing, ensuring GDPR compliance while maintaining trust.
4. Cross-Border Legal Validation
Credentials stored in EUDI Wallets meet EU legal standards, enabling secure use in any country.
5. Integrated Regulatory Alignment
eIDAS 2.0 rules are built directly into wallet functionality, helping service providers remain compliant.
6. Interoperability at Scale
Wallets communicate seamlessly with national eID systems, government portals, and private services.
7. Real-Time Identity Verification
Instant authentication speeds up service delivery while protecting data integrity.
8. Auditability & Compliance Monitoring
Immutable logs of identity verification activities support audits and transparency requirements.
Use Cases of EUDI Wallets Under eIDAS 2.0
Public Service Access: Reduce bureaucracy by enabling instant government portal access with stored credentials.
Cross-Border Healthcare: Securely share health records during treatment in another EU country.
Online Banking: Streamline KYC onboarding with verified government-issued identity credentials.
Academic Credential Verification: Prevent fraud by verifying degrees and certifications in real time.
Age Verification: Prove eligibility without revealing full birth date for regulated sectors.
Digital Contract Signing: Complete legally binding agreements electronically.
E-Commerce Identity Verification: Minimize fraud with secure, cross-border retail onboarding.
The Future of EUDI Wallets in Europe
By November 2026, EUDI Wallets will be mandatory in all EU states. Forecasts predict 169 million wallets in circulation by 2026, doubling the reach compared to 2025. The roadmap includes deeper integration with public services, secure document sharing, digital payments, and enhanced biometric authentication.
Conclusion
EUDI Wallets are the core implementation of eIDAS 2.0, turning regulatory vision into practical tools that foster trust, privacy, and interoperability across Europe. They bridge legal requirements with real-world usability, removing barriers for citizens, businesses, and governments.
For organizations, adopting EUDI Wallet technology today means building secure, scalable identity verification systems that ensure compliance, improve operational efficiency, and deliver a better user experience for cross-border digital services.
