The EUDI Wallet in practice: Verified Call and wallet login
AI-generated, human-reviewed
Why this matters
With the eIDAS 2.0 regulation, the EU introduces the European Digital Identity Wallet (EUDI Wallet): a state-issued digital wallet that lets citizens identify themselves online — from proof of age to full identity verification. From 2027, many industries are obliged to accept the wallet as a means of identification, including banks, telecom providers and large platforms. Whoever starts integrating only then will face time pressure in a technically demanding ecosystem of new protocols and trust models.
We decided early on to work through this topic in running software rather than slide decks — with two applications covering real use cases.
EUDI Verified Call: video calls between verified people
A peer-to-peer call (video, audio, chat) in which both sides identify themselves via EUDI Wallet before connecting. The key detail: both parties see in advance which identity fields will be exchanged — the values themselves are only disclosed once both consent. This protects against vishing and identity fraud in situations where certainty matters: consultations, contract closings, dealings with authorities. The application exists as an open-source core plus commercial pro extensions.
Wallet login: passwordless and pseudonymous
A proof of concept for logging in via EUDI Wallet based on OpenID4VP and SIOPv2 — including a simulated paywall for publishers. Users prove what is necessary (a valid subscription, being of age) without creating a password account and without disclosing more data than required. Dedicated issuer and verifier components run in containers and fit into existing system landscapes.
What this means for your project
Both projects produced solid knowledge of the EUDI ecosystem: protocols (OpenID4VP, OpenID4VCI, SIOPv2), certificate and trust chains, wallet compatibility and the limits of current reference implementations. We bring this knowledge to integration projects — from impact assessment to pilot operation.
