The European Identity Wallet is a digital wallet for storing and presenting identity attributes and credentials for cross-border use. It is designed to let a person authenticate and share selected data, such as identity details or attestations, under the rules of the applicable trust framework, with user consent and controlled disclosure.
What the European Identity Wallet is for
The European identity wallet is a cross-border identity wallet designed to let a person hold identity data and attestations, then present only the information needed for a transaction under the applicable trust framework and consent rules.
Its value is not just storage. The wallet is meant to support controlled disclosure, so the user can prove something about themselves without handing over a full identity record every time. That changes the trust model for public services, private relying parties and cross-border verification.
How the wallet changes identity verification
Traditional identity checks often depend on repeated logins, copies of documents or broad data collection. A wallet model shifts that to credential presentation, where the holder can reuse verified attributes across services while the relying party checks the wallet proof rather than a scanned document or a manually entered profile.
This matters because the security boundary moves from a central account database to the presentation flow, the wallet app, the issuer of the credential and the relying party that accepts it. If any of those parties mishandle trust, the assurance of the interaction drops quickly.
For a broader view of how wallets, eID and verifiable credentials fit together, see Digital Identity, eID and Identity Wallets Guide.
Trust framework, consent and selective disclosure
The European Identity Wallet is governed by the rules of the relevant trust framework, which means the wallet is not a free-form data store. What can be requested, what can be released and how the relying party is registered all shape whether a presentation is legitimate and trustworthy.
Selective disclosure is central here. Instead of revealing an entire identity document, the wallet can support sharing only a specific attribute or attestation, reducing unnecessary exposure of personal data and limiting what a relying party can collect.
Those controls are why the wallet has both privacy and interoperability significance: cross-border use depends on common trust, but user consent and disclosure limits prevent the wallet from becoming a universal surveillance channel.
For the regulatory structure behind those duties, see eIDAS 2.0 and the European Digital Identity Framework Guide and the official eIDAS 2.0 , EU Digital Identity Framework.
Wallet security and assurance considerations
A wallet is only as trustworthy as its enrollment, binding and presentation protections. If a wallet instance is cloned, a device is compromised, or a presentation is relayed to the wrong party, the assurance value of the credential can be lost even when the underlying identity proof was originally strong.
Because the wallet is a high-value container for identity attributes and credentials, attackers may target onboarding, token theft, device compromise, fake wallet apps or consent manipulation. The operational question is not merely whether the wallet exists, but whether its bindings, issuers and relying parties are verified end to end.

What practitioners should understand about implementation
The practical issue for issuers, wallet providers and relying parties is governance as much as technology. They need consistent acceptance rules, clear reliance decisions and a way to verify that the wallet interaction really matches the declared trust model and the intended user journey.
Practitioners should also treat device trust and credential binding as first-class concerns, because cross-border portability increases the blast radius of a weak wallet implementation. If the wallet is accepted too loosely, it becomes easy to misuse; if it is implemented too rigidly, the interoperability promise fails.

Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP API Security Top 10 addresses the attack surface, NIST SP 800-63 and CSA Cloud Controls Matrix set the technical controls, and ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-63 | IA-2 — Identification and Authentication (Organizational Users) | Wallet use depends on strong user authentication for cross-border identity presentation. |
| Recommendation — Require phishing-resistant authentication before releasing wallet-held identity data. | ||
| ISO/IEC 27001:2022 | A.5.16 — Identity management | Wallet ecosystems rely on governed identity lifecycle and trustworthy identity assignment. |
| A.5.17 — Authentication information | Wallet credentials and presentation secrets must be protected throughout use and recovery. | |
| Recommendation — Define ownership and lifecycle rules for wallet identities and relying-party trust. Protect wallet secrets and recovery materials as controlled authentication information. | ||
| CSA Cloud Controls Matrix | IAM — Identity & Access Management | Wallet acceptance, disclosure and trust framework governance are core IAM concerns in cloud services. |
| Recommendation — Apply IAM controls to wallet acceptance, disclosure and relying-party access decisions. | ||
| OWASP API Security Top 10 | API2 — Broken Authentication | Wallet presentation flows often depend on APIs whose authentication must remain trustworthy. |
| Recommendation — Validate wallet-facing APIs so authentication cannot be bypassed or replayed. | ||
