eIDAS 2.0 Digital Identity Wallet: Compliance Requirements for E-Signature Providers 2026

The original eIDAS Regulation (EU) No 910/2014 established a legal framework for electronic identification and trust services across the European Union, creating mutual recognition for electronic signatures, seals, timestamps, and certificates. Whilst eIDAS 1.0 successfully harmonised trust service provider requirements and enabled cross-border recognition of qualified electronic signatures, it contained significant limitations preventing comprehensive digital identity adoption.

eIDAS 2.0, formally Regulation (EU) 2024/1183 published April 30, 2024 and entering force May 20, 2024, fundamentally expands the regulatory scope. The centrepiece: mandatory EU Digital Identity Wallets enabling citizens, residents, and businesses to securely store and share verified credentials with public and private sector services throughout the Union.

• Fragmented Identity Schemes: Member States operated independent national electronic identification systems with varying security levels and limited interoperability, creating friction for cross-border services.
• Private Sector Exclusion: The regulation primarily addressed public sector services, leaving private organisations without standardised frameworks for accepting government-issued digital identities.
• Limited Attribute Verification: Beyond basic identity, verifying professional licenses, educational qualifications, or corporate roles required separate processes outside the eIDAS framework.
• User Experience Friction: Repeated identity verification for different services created abandonment, particularly in electronic signature workflows requiring qualified certificates with typical industry processing times of 24-48 hours.

• Universal Wallet Mandate: All Member States must provide free, EU Digital Identity Wallets containing government-verified credentials, ensuring consistent availability across the Union.
• Mandatory Acceptance: Specified services—including very large online platforms and qualified trust service providers issuing qualified signatures—must accept EUDI Wallets when users present them for strong authentication.
• Verifiable Credentials Framework: Integration of W3C Verifiable Credentials and selective disclosure capabilities enables users to share only necessary attributes (e.g., "over 18" without revealing birthdate) whilst maintaining privacy.
• Cross-Border Interoperability: The Architecture Reference Framework (ARF) establishes common technical standards ensuring wallets issued by one Member State function seamlessly across all others, critical for international e-signature services.
• Expanded Trust Services: Introduction of Qualified Electronic Attestations of Attributes (QEAAs) enables trusted verification of professional qualifications, corporate roles, and other credentials beyond basic identity—directly enhancing attribute-based signing authority for contracts.

The EUDI Wallet operates on a decentralised, privacy-preserving model fundamentally different from centralised identity databases. Understanding this architecture is essential for e-signature providers designing wallet integration.

• User-Controlled Storage: Credentials reside on users' devices (smartphones, tablets) rather than centralised servers, ensuring users maintain control over personal data consistent with GDPR principles.
• Cryptographic Security: Public key infrastructure enables cryptographic proofs of credential authenticity without revealing unnecessary information, supporting selective disclosure for privacy protection.
• Multi-Credential Support: Wallets store diverse credential types: government-issued identity (passport, national ID), professional licenses, educational certificates, payment authorisations, health records, and corporate attributes.
• Offline Capability: Certain verification scenarios function without internet connectivity, though electronic signature workflows typically require online validation against trust lists.

The W3C Verifiable Credentials standard structures how credentials are issued, stored, and presented:

1. Issuance: Government agencies, educational institutions, professional bodies, or qualified trust service providers issue digitally-signed credentials to users' wallets containing verified attributes.
2. Storage: Users control which credentials reside in their wallets, with cryptographic proofs ensuring tampering detection.
3. Presentation: When accessing services requiring authentication (e.g., initiating qualified signature requests), users select relevant credentials to share with the relying party (e-signature platform).
4. Verification: The relying party cryptographically verifies credential authenticity against issuer signatures and checks issuer status against EU trust lists, completing authentication without direct contact with credential issuers.

Beyond identity verification for electronic signatures, EUDI Wallets will revolutionise payment authentication and open banking services by enabling users to securely share financial credentials with third-party providers whilst maintaining control over personal data—creating opportunities for integrated contract and payment workflows.

eIDAS 2.0 imposes different obligations depending on provider type. Qualified Trust Service Providers issuing qualified signatures face mandatory requirements, whilst other platforms may voluntarily adopt wallet integration for competitive advantage.

Qualified trust service providers offering qualified certificate issuance for qualified electronic signatures (QES) must accept EUDI Wallets as an authentication mechanism when users present them. This obligation applies specifically to identity verification steps during certificate issuance.

• Wallet Authentication Integration: Platforms must implement technical interfaces accepting wallet-based identity credentials as valid identity proof equivalent to traditional methods (video identification, in-person verification, national eID schemes).
• Credential Verification Capability: Systems must cryptographically verify credentials against issuer signatures and validate issuer status through EU trust lists, ensuring credential authenticity and current validity.
• Attribute Processing: When users share credentials containing identity attributes (name, date of birth, address, nationality), providers must securely extract, validate, and incorporate these into qualified certificate generation workflows.
• Audit Trail Requirements: Comprehensive logging of wallet authentication events, credential verification results, and attribute extraction processes to demonstrate compliance during supervisory audits and conformity assessments.
• Privacy Protection: Processing only attributes necessary for certificate issuance consistent with GDPR data minimisation principles, avoiding retention of excessive wallet credential data.

QTSPs may be authorised to offer Qualified Electronic Attestations of Attributes (QEAAs) under forthcoming implementing regulations addressing attestation frameworks.

E-signature platforms accepting signatures (but not necessarily issuing qualified certificates) function as relying parties in the EUDI Wallet ecosystem, with distinct but related obligations.

• Very Large Online Platforms: Services meeting VLOP designation under the Digital Services Act must accept EUDI Wallets for strong authentication when users present them.
• Voluntary Adoption: Other e-signature platforms may choose wallet support to enhance user experience, reduce friction, and gain competitive advantage without regulatory mandate—though market pressure may effectively require adoption.

• Wallet Interface Implementation: Developing authentication flows triggering wallet presentation requests via standardised protocols defined in the Architecture Reference Framework (ARF) specifications.
• Selective Disclosure Support: Requesting only necessary attributes for specific transactions (e.g., legal capacity verification without full identity disclosure) to respect privacy whilst meeting authentication needs.
• Trust Framework Participation: Registering as relying parties within national frameworks, potentially requiring conformity assessments depending on Member State implementation approaches and service risk classifications.

Implementing EUDI Wallet compatibility presents substantial technical complexity, particularly given incomplete specifications and December 2026 deadlines.

Traditional e-signature authentication relies on username/password, email verification, SMS OTP, or national eID schemes with established integration patterns. Wallet-based authentication introduces fundamentally different flows.

• Protocol Compatibility: Ensuring authentication interfaces align with ARF specifications , which continue evolving throughout 2025-2026
• Fallback Mechanisms: Maintaining traditional authentication methods for users without wallets or experiencing technical issues, avoiding service disruption
• Mobile vs Desktop: Designing flows accommodating both mobile wallet apps (primary use case) and desktop environments potentially requiring QR code scanning for cross-device authentication
• Error Handling: Managing verification failures (expired credentials, revoked issuers, cryptographic errors) gracefully whilst maintaining security

Solution Approach: Implementing modular authentication architectures with abstraction layers isolating wallet-specific logic from core business processes, enabling protocol updates without major system refactoring.

W3C Verifiable Credentials use JSON-LD or JWT formats with embedded cryptographic proofs. Processing these securely requires specialised capabilities.

• Cryptographic Verification Libraries: Integrating software libraries supporting relevant signature algorithms (ECDSA, RSA, EdDSA) and proof formats (JSON Web Signatures, Linked Data Proofs)
• Trust List Integration: Maintaining current copies of EU trust lists containing authorised credential issuers (Member State identity authorities, qualified trust service providers, authorised attribute providers) and checking issuer status during verification
• Attribute Extraction: Parsing credential structures to extract specific attributes (name, birthdate, professional licenses) whilst validating data types and formats match expected schemas
• Revocation Checking: Querying credential revocation services (potentially via Online Certificate Status Protocol or distributed ledgers) ensuring credentials remain valid at verification time
• Selective Disclosure Validation: When users employ selective disclosure (revealing only subset of credential attributes), verifying cryptographic proofs demonstrate selective attributes derive from complete credentials without exposing unrevealed data
• Implementation Challenge: Specifications for credential formats, revocation mechanisms, and selective disclosure implementations remain in development, forcing parallel development across multiple candidate standards.

With 27 Member States issuing wallets, ensuring consistent functionality across all implementations presents significant testing and operational challenges.

• Credential Format Harmonisation: All Member States must issue credentials conforming to Architecture Reference Framework (ARF) specifications
• Testing Infrastructure: Participating in pilot programmes validating interoperability before production
• Ongoing Updates: Establishing procedures monitoring implementing regulation updates

Successful eIDAS 2.0 adaptation requires strategic thinking beyond technical compliance.

Providers implementing wallet compatibility early gain market differentiation, particularly for cross-border services and government contracts, with streamlined authentication improving conversion rates.

• Core infrastructure ensuring fundamental wallet compatibility before advanced features
• Selective enhancement identifying high-value use cases warranting sophisticated credential processing
• Ecosystem participation joining industry consortia and pilot programmes providing early specification access

Industry estimates suggest budgeting for API development (€50-150k), certification updates (€20-40k), and pilot programme participation. However, long-term operational savings from streamlined identity verification often offset initial investment within 18-24 months through reduced manual verification costs and improved conversion rates.

• Timeline Uncertainty: Implementing flexible architectures accommodating specification changes as standards finalise throughout 2025-2026
• Adoption Rate Variables: Planning for scenarios where 80% wallet adoption by 2030 progresses slower than targets, necessitating continued traditional authentication support
• Regulatory Evolution: Monitoring policy developments potentially expanding mandatory acceptance requirements

eIDAS 2.0 represents the most significant digital identity transformation in European regulatory history, fundamentally reshaping how businesses verify identity and establish trust in digital transactions. For electronic signature providers, this transformation presents both substantial compliance obligations and strategic opportunities.

• Early engagement with technical specifications and implementing regulations as they develop
