Glossary · EU Digital Identity eIDAS 2.0 (electronic IDentification, Authentication and trust Services 2.0)
The 2024 update to EU electronic identity regulation that mandates a European Digital Identity Wallet for every EU citizen by 2026.
## What eIDAS 2.0 actually does
eIDAS 2.0 is shorthand for Regulation (EU) 2024/1183, which amends the original eIDAS Regulation (EU) No 910/2014. The main change: it mandates the **European Digital Identity Wallet (EUDI Wallet)** — a smartphone-based application that every EU member state must offer to its citizens by the end of 2026.
The wallet allows EU residents to:
- Store and present digital credentials (national ID, driving license, diplomas, qualifications, health cards)
- Authenticate to online services across borders
- Sign documents with qualified electronic signatures (QES)
- Make age verifications and other selective disclosures without revealing full identity
## Why this is foundational infrastructure
eIDAS 2.0 isn't just a privacy improvement — it's strategic infrastructure that addresses one of the largest sources of US dependency in European digital services: authentication.
In 2026, most European online services authenticate users through:
- Email + password (vulnerable, requires recovery flows)
- Sign in with Google / Apple / Microsoft (US dependency)
- Facebook Login (US dependency, ongoing)
- National eID where available (BankID, MitID, itsme, etc., fragmented across countries)
The EUDI Wallet creates a single pan-European authentication infrastructure that works across borders, replaces US identity-as-a-service dependencies, and is operated by member states rather than commercial entities.
## How the technical architecture works
The wallet operates on a decentralized model:
- **Credentials are stored on the user's device**, not in a central government database
- **Verifiers cannot track users across services** — the regulation explicitly prohibits cross-service profiling
- **Selective disclosure** — users can prove a single fact (e.g., "I'm over 18") without revealing other information
- **Biometric authentication** for wallet access stays on-device, never transmitted to verifiers
The cryptographic primitives use established standards (ISO/IEC 18013, OpenID4VC) so the wallet interoperates with existing digital identity infrastructure.
## What changes for businesses
For businesses operating in the EU, eIDAS 2.0 creates two opportunities and one obligation:
**Opportunity 1: Replace authentication providers.** Services that currently require Google/Apple Sign-In can offer EUDI Wallet authentication instead. Lower vendor lock-in, stronger privacy posture, no transatlantic data transfers for authentication metadata.
**Opportunity 2: Replace KYC providers.** Identity verification processes that currently route through US identity verification services (Jumio, Onfido) can use the EUDI Wallet directly. Faster, cheaper, more accurate, EU-jurisdictional.
**Obligation: Accept the wallet for authentication.** Large online platforms operating in the EU (the Digital Markets Act gatekeepers and other "very large online platforms") will be required to accept EUDI Wallet authentication once member state implementations are deployed.
## Qualified Electronic Signatures (QES)
A specific eIDAS provision worth highlighting: **Qualified Electronic Signatures** under eIDAS have full legal equivalence to handwritten signatures across all 27 EU member states.
For European legal practice, this matters operationally. A document signed via QES:
- Is admissible as evidence in any EU member state's courts without re-signing
- Has presumed integrity (the burden of proof shifts to whoever challenges authenticity)
- Carries the same legal weight as a handwritten signature
QES requires a Qualified Trust Service Provider (QTSP) — a regulated entity that has been certified by an EU national supervisory authority. Examples include [Yousign](/en/alternatives/yousign-vs-docusign/) (France), [Signicat](/en/alternatives/signicat-vs-okta/) (Norway, EEA), and various others.
For European businesses, choosing QES via EU QTSPs over US-based e-signature platforms (DocuSign, HelloSign) provides stronger legal validity at lower regulatory friction.
## Timeline
- **2024**: eIDAS 2.0 regulation adopted
- **2025**: Pilot deployments in multiple EU member states
- **End of 2026**: All EU member states must offer EUDI Wallet to citizens
- **2027-2028**: Expected widespread adoption across EU online services
- **Late 2026 onwards**: Mandatory acceptance by very large online platforms
For European businesses planning identity and authentication infrastructure beyond 2026, eIDAS 2.0 should be a primary architectural consideration. Building today around US identity providers creates technical debt that the EUDI Wallet rollout will increasingly highlight.
