Two months ago we announced end-to-end OpenID4VC support in private beta. With Yivi 8.0 and irmago 1.0 shipping today, those protocols reach production — and the foundation underneath them has finally caught up.

This release is the structural moment Yivi stops being an IRMA wallet that speaks OpenID and becomes a credential-format-agnostic wallet that happens to also speak IRMA. It is the single biggest milestone in our transition toward a crypto-agile EUDI wallet.

With irmago 1.0 (currently in beta), the command-line tool you've been calling irma is shipped as yivi, and the Go package that issuer and verifier requestor servers import has moved with it. This post is for anyone running irma server, irma session, or the Docker image in production, and for anyone whose service imports github.com/privacybydesign/irmago to construct or sign session requests — what changes, what stays the same, and how to migrate.

After shipping OpenID4VP support last year and migrating all Privacy by Design issuers to SD-JWT VCs earlier this year, today we're closing the loop: Yivi now supports both OpenID4VCI and OpenID4VP. Issuers and verifiers can integrate with Yivi entirely using open standards.

We're opening a private BETA and inviting organizations to be among the first to integrate.

Digital driving licenses are being introduced across Europe and beyond, but they don’t all work the same way.

As part of my Master's thesis, I researched the progress and current state of digital driving licenses, also known as mobile driving licenses (mDLs). I compared Austria, Australia, and Germany to understand how these systems differ in practice, and what that means for wallet-based identification.

Austria and Australia, specifically New South Wales (NSW), are both relatively advanced in implementing mDLs. Austria stands out as a European frontrunner, with mDLs aligned with ISO standards and accepted by the police. Australia, while non-European, also has a working system, but with notable differences in design.

Germany, in contrast, has not yet introduced mDLs. Adoption is slower, and both legal and cultural approaches are more cautious. Together, these countries provide a useful comparison on multiple aspects: operational vs. non-operational systems, EU vs. non-EU contexts, and fast vs. slow adoption.

The Yivi team is working hard on Yivi itself to become EUDI compliant, but besides Yivi we're also working hard on other projects like PostGuard. In this blog we'll tell you about PostGuard and what PostGuard's plans are for the coming year. We hope to get you just as excited about PostGuard as we are. And that when you want to send files, you'll do it with PostGuard of course!

A security analysis of the EU Age Verification Wallet reveals a privacy-first design with a critical trust gap that undermines its security guarantees.

We're pleased to announce that all Privacy by Design Foundation issuers now issue SD-JWT Verifiable Credentials alongside traditional Idemix credentials. This marks a significant milestone in Yivi's transition to becoming a fully EUDI-compliant wallet.

We're excited to announce a new feature that makes managing your digital identity even simpler: you can now issue your phone number and email address without ever leaving the Yivi app.

We're thrilled to announce that Yivi now supports ID-cards and Dutch Driver Licenses as credentials. This expansion significantly broadens Yivi's international reach and makes the platform more accessible to users worldwide.

According to our mission, we are committed to transparency and accountability. This post-mortem is part of that commitment, detailing the events surrounding the outage of the 7th of January 2026.

Summary of the impact​

We experienced significant degradated user experience on the 7th of January 2026, which affected our services for approximately 4 hours. During this time, users experienced inconsistent success rates in onboarding the Yivi app and or issuing credentials to them. The issue was caused by key rotation of the Yivi scheme and successive issues which arose from rotating the key.
