eIDAS 2.0 significantly affects the banking sector by introducing stronger, standardized digital identity requirements that banks must both accept and integrate into their services. The regulation requires financial institutions across the EU to recognize the European Digital Identity Wallet (EUDI Wallet) for identity verification, fundamentally changing how banks handle onboarding, authentication, and compliance. Below, we answer the most important questions banks are asking right now.

What changes does eIDAS 2.0 bring to identity verification in banking?

eIDAS 2.0 raises the bar for digital identity verification in banking by establishing a single, EU-wide standard that replaces the fragmented national approaches that have existed until now. Banks must accept verified identity data from EUDI Wallets, meaning the identity a customer has already established with their government or another trusted provider becomes valid across borders and across services.

Under the original eIDAS regulation, EU member states were required to recognize each other’s notified electronic ID schemes, but there was no obligation to create a national eID or make it interoperable with private sector services. eIDAS 2.0 closes that gap. It extends the framework to the private sector and introduces a wallet-based model that puts verified, cryptographically secured identity data directly into the hands of users.

For banks, this means identity verification can no longer rely solely on proprietary processes or locally accepted documents. The standard for what counts as a verified identity becomes EU-wide, which is both a technical shift and a compliance obligation. Banks operating across multiple European markets will benefit from this harmonization, since a single integration with the EUDI Wallet ecosystem can replace multiple country-specific identity verification flows.

How does the EUDI Wallet affect KYC and onboarding processes?

The EUDI Wallet has the potential to make KYC and customer onboarding significantly faster and less repetitive. Instead of asking a new customer to upload documents, submit selfies, and wait for manual review, a bank can request verified identity attributes directly from the customer’s wallet. The data has already been verified at a high assurance level, which means the bank can rely on it without repeating the full verification process from scratch.

This is one of the most practical shifts eIDAS 2.0 brings to financial services. Today, customers often go through the same identity checks multiple times, once with their bank, again with their insurer, and again with another financial provider. The EUDI Wallet introduces the concept of reusable identity: a customer verifies once, and that verified identity can be reused across services with their explicit consent.

For onboarding specifically, this removes a major source of friction. Lengthy identity checks are one of the leading causes of onboarding abandonment. When a customer can share verified attributes from their wallet in seconds, conversion rates improve and the time-to-trust shrinks considerably. At the same time, banks retain full auditability, since every data-sharing event is logged and consent-based.

It is worth noting that KYC and Anti-Money Laundering (AML) obligations remain in place. The EUDI Wallet does not replace compliance requirements. What it does is provide a higher-quality, more reliable data source to meet those requirements more efficiently. Banks still need to assess risk, apply due diligence, and maintain records. The wallet simply makes the identity verification step of that process more trustworthy and less burdensome for both the bank and the customer.

Which banking services must accept the EUDI Wallet under eIDAS 2.0?

Under eIDAS 2.0, banks and other financial institutions that offer services requiring identity verification must accept the EUDI Wallet as a valid means of identification. This obligation applies specifically to services that require strong authentication or identity verification, including opening a bank account, accessing online banking, and initiating certain payment flows.

The large-scale pilot programs launched by the European Commission have already tested several banking-specific wallet use cases. Opening a bank account online is one of the eleven priority use cases being piloted, where the wallet enables identity verification without requiring the customer to repeatedly provide personal information. Payment authentication is another tested use case, with the NOBID Consortium specifically piloting the use of EUDI Wallets for authorizing payments across Nordic, Baltic, Italian, and German participants.

In practical terms, banks need to evaluate which of their digital services fall within the scope of this obligation. Services that currently rely on eID-based login or strong customer authentication under PSD2 are natural starting points. The intersection of eIDAS 2.0 and PSD2 is particularly relevant for financial services, since strong customer authentication requirements and wallet-based identity verification will increasingly overlap. For a deeper look at how this plays out, the topic of digital identity in financial services is worth exploring in detail.

What compliance obligations does eIDAS 2.0 create for financial institutions?

eIDAS 2.0 creates several concrete compliance obligations for financial institutions. The most significant is the requirement to accept the EUDI Wallet for identity verification in services that fall within the regulation’s scope. Beyond acceptance, banks must ensure their systems can technically interact with wallet-based identity data, which involves implementing the necessary protocols and meeting interoperability standards.

Key compliance areas include:

• Wallet acceptance: Banks providing online services that require identity verification must be capable of accepting identity attributes presented via the EUDI Wallet.
• Data minimization: The wallet is designed to share only the specific attributes a service needs. Banks must align their data requests with this principle, requesting only what is necessary for a given transaction or onboarding step.
• Interoperability standards: Banks must implement the technical standards defined in the Architecture and Reference Framework that underpins the EUDI Wallet ecosystem.
• Audit and record-keeping: Consent-based data-sharing events must be logged appropriately to maintain compliance with both eIDAS 2.0 and GDPR requirements.
• AML and KYC alignment: Wallet-verified identity data must be integrated into existing AML and KYC workflows in a way that satisfies regulatory obligations under those frameworks as well.

It is important to recognize that eIDAS 2.0 does not operate in isolation. Financial institutions are simultaneously navigating PSD2, GDPR, AML directives, and the upcoming AMLR 2027 requirements. eIDAS 2.0 adds another layer, but it also creates an opportunity to consolidate identity infrastructure in a way that serves multiple regulatory frameworks at once.

How should banks prepare their systems for eIDAS 2.0?

Banks should prepare for eIDAS 2.0 by starting with a gap analysis of their current identity verification infrastructure and mapping where wallet-based identity data will need to be accepted and processed. The goal is to identify which systems, APIs, and onboarding flows need to be updated to support EUDI Wallet interactions.

A practical preparation approach follows these steps:

1. Assess current identity infrastructure: Identify which services require identity verification and how those processes currently work. Map out where EUDI Wallet acceptance will be required.
2. Review the Architecture and Reference Framework: Understand the technical specifications that govern how EUDI Wallets present and share identity data. Your development and architecture teams will need to align with these standards.
3. Evaluate your relying party obligations: Banks acting as relying parties in the wallet ecosystem must register and meet specific requirements to request identity attributes from wallets. Understand what that registration process involves in your jurisdiction.
4. Update onboarding and authentication flows: Redesign relevant customer journeys to accommodate wallet-based identity sharing, including consent mechanisms and data minimization practices.
5. Align with AML and KYC teams: Ensure that wallet-verified identity data integrates cleanly into your compliance workflows. Define how high-assurance wallet data satisfies due diligence requirements.
6. Test and pilot: Where possible, engage with existing pilot programs or sandbox environments to test wallet integrations before full deployment.

Member states are legally required to make EUDI Wallets available to citizens and businesses by 2026. That timeline means banks cannot afford to treat this as a distant future concern. Organizations that start their preparation now will be in a much stronger position than those that wait for full enforcement before acting. Exploring the right implementation approach early makes a measurable difference in how smoothly the transition goes.

What are the business opportunities eIDAS 2.0 creates for banks?

eIDAS 2.0 creates genuine business opportunities for banks that move beyond viewing the regulation purely as a compliance burden. The most immediate opportunity is faster, lower-friction onboarding that reduces customer drop-off and improves conversion rates. When identity verification becomes a matter of seconds rather than days, banks can compete more effectively on the quality of their digital experience.

Reusable identity is another significant opportunity. Banks are often among the first institutions to verify a customer’s identity at a high assurance level. Under the EUDI Wallet model, banks can potentially become trusted identity providers within the ecosystem, issuing verified credentials that their customers can reuse across other services. This positions banks as central players in the broader digital identity infrastructure rather than passive participants.

Cross-border expansion also becomes more tractable. Today, entering a new European market often means building or procuring a country-specific identity verification solution. With a standardized EU-wide wallet, a bank that has integrated with the EUDI Wallet ecosystem can serve customers across member states without rebuilding its identity layer from scratch.

Finally, the overlap between eIDAS 2.0 and existing compliance frameworks creates efficiency gains. A bank that builds its identity infrastructure around wallet-based verification can potentially satisfy KYC, AML, PSD2 strong customer authentication, and eIDAS 2.0 requirements through a single, well-designed integration. That consolidation reduces operational complexity and long-term compliance costs. For organizations exploring what this looks like in practice, reviewing how other organizations have approached this can provide useful reference points.
