🇱🇺EUDI Wallet Luxembourg: What We Know So Far

What We Know About Luxembourg's EUDI Wallet

Luxembourg, with a population of 1 million, is preparing to implement the European Digital Identity Wallet as required by the eIDAS 2.0 regulation. While specific details about Luxembourg's EUDI Wallet implementation have not been officially announced, several facts are clear based on EU law and Luxembourg's existing digital infrastructure.

Legal Requirement (🟢 Verified)

Under the eIDAS 2.0 regulation (EU) 2024/1183, which entered into force in May 2024, all 27 EU member states must provide a European Digital Identity Wallet to their citizens by December 31, 2026. This is a binding legal requirement, not optional. Luxembourg must comply with this deadline.

Existing Authentication System (🟢 Verified)

Luxembourg currently operates LuxTrust, a national digital authentication system that enables citizens to access government services electronically. LuxTrust provides secure login for tax filing, social security, healthcare, and other public services. The EUDI Wallet will likely build upon or integrate with this existing LuxTrust infrastructure, using years of established digital identity experience.

Regulatory Deadline (🟡 Confirmed by Regulation)

The December 31, 2026 deadline is set by EU law. Luxembourg must provide a wallet that meets the technical specifications defined in the Architecture and Reference Framework (ARF) version 2.7.3, which standardizes functionality across all EU member states.

LuxTrust: Luxembourg's Established Digital Identity Provider

LuxTrust S.A. is a public-private partnership founded in 2005, jointly owned by the Luxembourg state and major financial institutions. It functions as Luxembourg's qualified trust service provider, issuing digital certificates for authentication and electronic signatures. LuxTrust occupies a central position in Luxembourg's digital economy — virtually every online banking session, government service interaction, and electronically signed contract in the country flows through LuxTrust's infrastructure.

LuxTrust Product Ecosystem

Over two decades, LuxTrust has developed a range of products tailored to different security needs and user preferences. The LuxTrust Token is a physical device that generates one-time passwords for two-factor authentication. The LuxTrust Signing Stick is a USB device containing a qualified certificate that enables legally binding electronic signatures directly from a computer. The LuxTrust Scan mobile app uses QR code scanning for authentication, and the LuxTrust Mobile app provides full smartphone-based authentication without any additional hardware.

This product diversity reflects the evolution of digital identity technology over time, but it also creates complexity for users who must understand which product they need. The EUDI Wallet promises to simplify this environment by consolidating identity verification, authentication, and electronic signing into a single standardized application. For Luxembourg, this could mean a significant reduction in the number of distinct identity products citizens need to manage — a welcome simplification even if the transition requires adjustment.

GouvID: Luxembourg's Government Mobile Identity App

In 2022, Luxembourg launched GouvID, a government-issued mobile identity application that allows citizens to authenticate for public services using their smartphone with biometric verification (face recognition or fingerprint). GouvID was developed by CTIE (Centre des Technologies de l'Information de l'Etat), the government agency responsible for state IT infrastructure. The app represented a deliberate move toward mobile-first digital identity, reducing reliance on physical LuxTrust tokens.

GouvID's architecture and purpose overlap substantially with what the EUDI Wallet is designed to do: provide a smartphone-based, government-issued digital identity credential. This makes GouvID a strong candidate for evolution into Luxembourg's EUDI Wallet. Rather than building a completely new application, Luxembourg could extend GouvID with the additional features required by eIDAS 2.0 — cross-border interoperability, verifiable credential storage, selective disclosure, and qualified electronic signatures. Whether the government chooses this evolutionary path or starts fresh with a new app is not yet publicly known, but the GouvID foundation provides a meaningful head start.

CTIE: The Technical Engine Behind Luxembourg's Digital Government

CTIE (Centre des Technologies de l'Information de l'Etat) is the Luxembourg government agency responsible for all state IT systems, from infrastructure and hosting to application development and cybersecurity. CTIE built and maintains GouvID, the MyGuichet.lu e-government platform, and the technical infrastructure that connects government systems. CTIE also operates the national IAM (Identity and Access Management) platform that sits behind CY-Login authentication for government services.

For the EUDI Wallet, CTIE is the natural lead agency for technical implementation. The center has direct experience building mobile identity applications (GouvID), managing trust infrastructure, and integrating identity systems with government services at scale. Luxembourg's small size is actually an advantage here: with a focused government IT organization and a limited number of public service endpoints to integrate, Luxembourg could potentially deploy its EUDI Wallet with fewer coordination challenges than larger member states with fragmented IT governance.

Luxembourg as EU Institutional Hub: Unique Cross-Border Dimensions

Luxembourg's role as a host for major EU institutions creates digital identity needs that few other countries share. The European Court of Justice, the European Investment Bank, the European Court of Auditors, Eurostat, and several European Commission directorates are headquartered in Luxembourg. These institutions employ staff holding passports from all 27 member states, creating a concentrated microcosm of the cross-border identity challenges the EUDI Wallet was designed to solve.

Beyond the EU institutional community, Luxembourg's workforce is remarkably international. Over 200,000 people commute daily from neighboring France, Belgium, and Germany to work in Luxembourg — making up nearly half the country's total workforce. These cross-border commuters must regularly interact with Luxembourg's government services, banking system, and healthcare infrastructure while maintaining ties to their home country's systems. The EUDI Wallet's mutual recognition across member states directly addresses this daily reality: a Belgian resident commuting to Luxembourg City could use their Belgian wallet for Luxembourg services without needing separate Luxembourg-specific credentials.

Luxembourg's financial sector further amplifies the cross-border dimension. The country is Europe's largest investment fund domicile and a major private banking center, serving clients from across the EU and beyond. Financial institutions routinely perform KYC checks for clients holding identity documents from dozens of different countries. A standardized EUDI Wallet credential could dramatically simplify this multi-jurisdiction identity verification process, replacing manual document handling with a cryptographically verified digital exchange.

MyGuichet.lu: The Digital Services Platform

MyGuichet.lu is Luxembourg's complete e-government platform, where citizens and businesses handle virtually all administrative interactions with the state. The platform covers tax filing (through integration with the Administration des contributions directes), social security management, business registration, building permits, civil status requests, and hundreds of other procedures. MyGuichet.lu currently requires authentication through LuxTrust products or GouvID, and serves as the primary digital touchpoint between Luxembourg's government and its residents.

The platform's complete coverage means that EUDI Wallet integration with MyGuichet.lu alone would provide wallet-based access to the vast majority of government digital services. Luxembourg's centralized approach to e-government — funneling most services through a single platform rather than separate departmental websites — simplifies the integration effort compared to countries where government services are scattered across dozens of independent systems. For residents, this means the EUDI Wallet could become a practical daily tool relatively quickly after launch, rather than requiring gradual service-by-service rollout.

What Is Not Yet Known

We believe in being honest about what information is not yet available. The following details have not been officially announced by Luxembourg authorities:

Official Wallet Name (⚠️ Not Yet Announced)

Luxembourg has not announced the official name for its EUDI Wallet. While "LuxTrust Wallet" is a logical name, this is speculation, not official confirmation. The wallet may integrate directly into the existing LuxTrust system or be branded separately.

Exact Launch Date (⚠️ Not Yet Announced)

Beyond the December 2026 regulatory deadline, Luxembourg has not provided a specific launch date, pilot schedule, or rollout timeline. Some countries announce phased launches (pilot first, then gradual rollout), while others plan immediate availability—Luxembourg's approach remains unclear.

Setup Process (⚠️ Not Yet Announced)

The activation process—how Luxembourg citizens will set up their digital wallet—has not been disclosed. It will likely require existing government-issued credentials (ID card, passport, or LuxTrust account), but the specific steps are unknown.

Expected Functionality Based on EU Standards

Even without Luxembourg-specific announcements, we know what functionality Luxembourg's EUDI Wallet must provide, because all EU member states must comply with the same technical specifications (ARF 2.7.3):

Core Features (🟢 Verified from ARF Specifications)

• Identity Verification: Store and present digital identity for government services, banking, and age verification
• Banking KYC: From January 1, 2027, all banks and financial institutions must accept EUDI Wallet for customer identification (mandatory)
• Government Services: Access tax filing, healthcare, social security, business permits, and other public services
• Age Verification: Prove age for restricted purchases without revealing full birth date
• Cross-Border Recognition: Luxembourg digital credentials recognized in all 27 EU member states
• Qualified Signatures: Sign legally binding documents digitally with the same legal force as handwritten signatures

What Should Luxembourg Citizens Do Now?

While waiting for official announcements, Luxembourg citizens can take the following steps:

1. Ensure you have a valid Luxembourg ID card or passport — these will likely be required to activate the digital wallet
2. Set up GouvID if you haven't already — Luxembourg's existing government mobile identity app is the closest current product to the EUDI Wallet, and getting comfortable with it now will prepare you for the transition
3. Review your LuxTrust products — if you use a physical LuxTrust Token or Signing Stick, consider that the EUDI Wallet may eventually replace the need for these devices
4. Monitor official sources — Check guichet.public.lu for government announcements
5. Don't worry about missing the deadline — The wallet is optional; you can continue using physical documents

Reassurance: All EU Countries Must Comply

If you're concerned about whether Luxembourg will deliver an EUDI Wallet, remember this: the December 2026 deadline applies equally to all 27 EU member states. Luxembourg is legally obligated to provide a wallet, just like every other country. The lack of public announcements does not indicate Luxembourg won't comply—many countries are developing wallets without extensive public communication until closer to launch.
