From Static Identity to Continuous Trust: Securing Europe's Digital Identity Wallets

Across Europe, digital identity is entering a new phase. 

With the European Digital Identity Framework (Regulation EU 2024/1183) and the upcoming rollout of the EU Digital Identity Wallet, digital identity is becoming the foundation of how citizens prove who they are across borders, sectors, and an ever-growing list of use cases.

For identity verification providers, this represents both a massive opportunity and a structural challenge.

Digital Identity Is Becoming Critical Infrastructure

National schemes like SPID in Italy have already shown what a unified identity layer can do. Millions of Italian users rely on it daily to access government portals, financial platforms, and regulated workflows. 

At the European level, the EU Digital Identity Wallet takes this much further. Every Member State is required to offer at least one wallet, built to common specifications, to all its citizens, residents, and businesses, with the goal of making at least one version available by the end of December 2026. 

The wallet will allow users to identify themselves to public and private services, store and share digital documents that range from mobile driving licenses and university diplomas to train tickets and gym memberships, and even create legally binding electronic signatures, all from a single app on their phone. Service providers connected to this ecosystem can be anything from banks and universities to pharmacies and telecom operators.

As adoption grows, digital identities will stop being a single product or structure and will become critical infrastructure, which can attract sophisticated attacks.

The Limits of One-Time Verification

Most IDV systems today are designed around two clear moments: onboarding, and the first authentication. This is where providers excel, with document verification, biometric checks, liveness detection, database validation, and, increasingly, verification of the contact details provided during enrollment, such as the user’s phone number and email address.

These controls are essential, but they are one-off checks by design. If the phone number, email address, device, or digital footprint linked to the user is not continuously assessed, vulnerability gaps remain.

Once an identity has been verified and a wallet has been issued, a fundamental question remains largely unanswered: is this identity still controlled by the same person? 

Credentials get phished, phone numbers get hijacked through SIM swap attacks, and email accounts get compromised. Devices change hands, get cloned, or get emulated. While credentials inside the wallet remain technically valid, the identity behind them is no longer trustworthy.

The Shift in the Threat Model

As digital identity wallets become more widely adopted, attackers are adapting and evolving. They are no longer focused on bypassing onboarding, rather they are targeting the existing, verified identity itself. This shift creates a new generation of risks: 

• Account takeover hits trusted identities that already enjoy elevated assurance levels and broader access;
• Identity-linked attributes such as email and phone can be quietly manipulated to redirect recovery flows; 
• Wallets can be abused for financial or administrative gain; 
• Fragmented controls across multiple providers can be exploited at the seams. 

The weakest point, in other words, is no longer identity creation, but identity persistence.

Fragmentation Creates Blind Spots

Europe's federated model, with multiple IDV providers, identity issuers, wallet providers, and relying parties, is a strength when it comes to scalability and competition. Different actors play distinct roles inside a shared technical framework, which keeps the ecosystem open and interoperable across borders.

But the same distributed architecture also creates fragmentation. Different onboarding standards, inconsistent verification depth, and limited visibility beyond the initial verification step are all real concerns. 

While each provider validates an identity at issuance, very few have visibility into what happens afterward. In a wallet-based ecosystem where the same identity is reused across many services, those gaps quickly become systemic blind spots.

From Verification to Continuous Trust

To secure digital identity wallets at scale, the model needs to evolve. The industry has to move from static verification and one-time assurance to continuous monitoring and dynamic risk assessment.

In practice, that means adding a layer of intelligence that operates beyond onboarding. By continuously assessing key identity signals such as email, phone number, IP address, and device data, and triggering additional checks whenever contact details linked to the wallet are changed, providers can detect account takeover or hijacking attempts before they succeed.

The new model should also enable continuous analysis of behavioral and usage patterns to identify anomalies, surface early indicators of compromise, and assess identity risk in real time during the moments that matter most, such as high-value transactions, sensitive document signing, or the sharing of credentials with a new relying party.

This is not something that is going to replace IDV, but rather extend it over time.

The Role of IDV Providers in This New Model

IDV providers are uniquely positioned to lead this transition. They already own the trust relationship at onboarding, manage identity assurance levels, and integrate deeply into regulated workflows. The natural next step is to expand from being identity verification providers to becoming identity trust providers.

That can mean embedding continuous monitoring capabilities directly into existing workflows, integrating external intelligence layers such as OSINT, behavioral signals, and device fingerprinting, offering real-time risk scoring APIs alongside verification, and giving relying parties the ability to make decisions not just on who the user is, but on how trustworthy that identity is at this exact moment.

Once a wallet is established and cryptographically bound to a device, it can become highly trustworthy. But this trust depends on two things: how confidently the issuer linked the wallet to the legitimate human during set-up, and how reliably that link is maintained over time. 

If the initial enrollment is compromised, the attacker walks away with a very strong credential tied to someone else's identity. If the enrollment was legitimate but the user is later phished, SIM-swapped, or has their device taken over, the credential remains technically valid while the identity behind it is no longer trustworthy. Either way, the wallet's cryptographic strength becomes a liability rather than a safeguard.

This is exactly the kind of challenge a solution like Trustfull is built to address.

How Trustfull Can Help

As a fraud prevention company built on digital footprint analysis, Trustfull helps organizations move from one-off identity checks to continuous, signal-driven risk assessment.

Trustfull’s platform silently analyzes hundreds of digital signals tied to phone numbers, email addresses, IP addresses, devices, browsers, and domains, with no impact on the user experience. That intelligence can sit alongside an IDV stack at every critical moment in the customer journey, from onboarding and login through to active sessions.

For the wallet era specifically, that translates into a few concrete capabilities. Trustful can:

• flag when the contact details provided at enrollment show little digital footprint activity or appear inconsistent with the identity being claimed, helping stop fraudulent wallet issuance at the source;
• detect when an email address or phone number added as contact details for an existing wallet user show high-risk indicators, such as recent creation, SIM swap activity, disposable services, or connections to known fraud patterns;
• identify when access attempts come from new or high-risk IP addresses linked to proxies, VPNs, datacenters, remote desktop tools, or locations inconsistent with the user’s normal behavior;
• spot when device fingerprints suggest emulation, spoofing, or unusual sharing.

For IDV providers, banks, telcos, public administrations, and other relying parties preparing for the EU Digital Identity Wallet rollout, this kind of layer is what turns a static credential into an adaptive trust system.

Securing the Future of Europe's Digital Identity

The success of the EU Digital Identity Wallet will not depend only on usability or adoption, but also on trust at scale.

Without continuous monitoring, digital identity wallets risk becoming high-value targets for account takeover, static credentials in a dynamic threat environment, and single points of failure across whole ecosystems. With continuous monitoring in place, they can become something very different: adaptive trust systems, resilient identity layers, and real-time decision engines for secure digital interactions.

FAQs

What is the EU Digital Identity Wallet?

It is a personal digital wallet that every EU Member State will offer to its citizens, residents, and businesses. Built to common European specifications, it lets users prove who they are online, store and share digital documents such as mobile driving licenses, diplomas, or travel passes, and create legally binding electronic signatures. The wallet is part of the European Digital Identity Framework, Regulation (EU) 2024/1183, which entered into force in May 2024.

When will the EU Digital Identity Wallet be available?

Each Member State is required to make at least one version of the wallet available, and the deployment timeline targets a launch by 2026, with Large Scale Pilots already testing real-world use cases like banking, telecom, payments, travel, and education.

Does the wallet replace existing national IDV solutions?

No. The wallet is designed to complement and interoperate with national identification schemes and the broader IDV ecosystem. Identity verification providers will continue to play a central role in onboarding, assurance leveling, and trust management. What changes is the scope of the trust they need to maintain over time.

Why is continuous monitoring becoming so important?

Because the attack surface has shifted. Onboarding is well defended in most mature IDV systems, so attackers are increasingly targeting already verified identities through phishing, SIM swap, device compromise, and social engineering. Continuous monitoring closes the gap between the moment of verification and everything that happens afterward.

How does Trustfull fit into this picture?

Trustfull provides real-time, silent risk assessment based on digital signals from phones, emails, IPs, devices, browsers, and domains. It works alongside IDV providers and relying parties to detect risk during sign-ups, logins, and active sessions, helping the wider ecosystem move from static, one-time verification to continuous trust.

Is Trustfull GDPR compliant?

Yes. Trustfull is GDPR compliant and relies on non-invasive analysis of publicly available digital signals, with no friction added to the end-user experience.
