A digital ID wallet earns trust by sharing less: show only the one fact a verifier needs, and make every disclosure the user's choice.

**TL;DR.** The EU Digital Identity (EUDI) Wallet lets citizens store and present credentials like a driver's license or ID. A good wallet UI is privacy-first: selective disclosure (share only the needed attribute), clear consent before every share, secure on-device storage, and an auditable history. Build it from a free VP0 design, lean on Apple's secure authentication and storage, and never over-collect. The whole value is sharing less, verifiably.

The EU Digital Identity (EUDI) Wallet, driven by the eIDAS 2.0 regulation, lets people store and present official credentials (national ID, driver's license, diplomas) from their phone. The short answer: build a privacy-first wallet UI from a free VP0 design built around selective disclosure, explicit consent before every share, secure on-device storage, and a clear history. This is a major mandate: the European Commission aims for [80%](https://commission.europa.eu/strategy-and-policy/priorities-2019-2024/europe-fit-digital-age/european-digital-identity_en) of citizens to be able to use a digital ID wallet by 2030, so getting the trust model right matters.

## Privacy is the product

The point of a verifiable credential wallet is to share less, not more. If a bar needs to know you are over 18, the wallet should prove exactly that, not reveal your name, address, and birth date. So selective disclosure is the core feature: the user picks (or confirms) the single attribute a verifier requested, and nothing else leaves the device. Every share needs explicit, in-context consent showing who is asking and for what. Credentials must be stored securely and protected by device authentication, and a history should let users see what they shared, with whom, and when. Apple's [Human Interface Guidelines](https://developer.apple.com/design/human-interface-guidelines/) on privacy and clarity apply throughout.

## Build it from a free design

VP0 is a free iOS design library for AI builders. Pick a wallet, card, or detail design, copy its link, and have Cursor or Claude Code rebuild it in SwiftUI. The credentials themselves should sit in secure storage protected by Face ID or Touch ID, present each as a clear card with its issuer and validity, and gate every presentation behind a consent sheet that names the verifier and the requested attribute. Use Apple's [PassKit and Wallet](https://developer.apple.com/documentation/passkit) patterns as a reference for how identity cards should feel, and pair credential unlock with strong device authentication. The hard rule: never over-collect or log more than necessary, minimization is both the law and the point. For the credential pattern more broadly, see [wallet verifiable credential UI template](/blogs/wallet-verifiable-credential-ui-template/), and for the biometric unlock, see [passkey creation biometric UI mobile](/blogs/passkey-creation-biometric-ui-mobile/).

## Wallet UI building blocks

Each part enforces privacy and trust.

| Part | Job | Privacy rule |
|---|---|---|
| Credential card | Show issuer and validity | Clear, verifiable source |
| Selective disclosure | Share one attribute | Reveal only what is asked |
| Consent sheet | Confirm each share | Name the verifier and request |
| Secure storage | Protect credentials | Device auth, on-device |
| Share history | Auditability | What, with whom, when |

## Common mistakes

The first mistake is over-sharing: revealing a whole ID when a single attribute would do, which defeats the purpose. The second is silent or vague consent, the user must clearly see who is asking and for what. The third is weak storage, credentials must be protected by device authentication, not sitting in plain storage. The fourth is no share history, so users cannot audit their disclosures. The fifth is collecting or logging more than needed on your side; minimization is mandatory, not optional. Trust is the entire value here.

## A worked example

Say a user needs to prove they are over 18 to a service. Your VP0-built wallet shows their credentials as clear cards. The verifier requests only the over-18 attribute; a consent sheet names the verifier and the single request, and the user approves with Face ID. Only that one proof is shared, nothing else, and it is recorded in a history the user can review. Credentials stay in secure storage, gated by biometrics. The user shared the minimum, verifiably, and stayed in control. For the broader credential foundations, see [wallet verifiable credential UI template](/blogs/wallet-verifiable-credential-ui-template/), and to wrap the wallet's first run in clear motion, see [Lottie animations for onboarding screens free](/blogs/lottie-animations-for-onboarding-screens-free/).

## Key takeaways

- The EU Digital Identity Wallet is a major mandate; build it privacy-first.
- Make selective disclosure the core feature: share only the attribute requested.
- Require explicit, in-context consent that names the verifier and the request.
- Store credentials securely, protected by Face ID or Touch ID, on device.
- Keep a share history and never over-collect; minimization is the point and the law.

## Frequently asked questions

What is the EU Digital Identity Wallet? It is an EU initiative under eIDAS 2.0 for a phone-based wallet that stores and presents official credentials like an ID or driver's license, with the goal of wide citizen availability by 2030.

How do I design a digital identity wallet UI? Build it from a free VP0 design around selective disclosure, an explicit consent sheet for every share, secure on-device storage protected by biometrics, and a clear share history.

What is selective disclosure? It means sharing only the specific attribute a verifier needs, such as proof you are over 18, without revealing your full identity. It is the core privacy feature of a credential wallet.

How should credentials be stored? In secure on-device storage protected by device authentication (Face ID or Touch ID), never in plain storage, and you should never collect or log more attributes than strictly necessary.
