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.

No more app-switching​

Previously, adding these credentials to your Yivi wallet meant visiting an external website, starting the issuance process there, and switching back to the app to complete it. It worked, but we knew we could do better.

Now, the entire process happens inside Yivi. Open the app, tap to add your phone number or email, and you're done in seconds.

How it works​

Adding your phone number is straightforward:

1. Select "Add phone number" in the app
2. Enter your number with your country code
3. Tap "Send sms" to receive a verification code
4. Enter the code that arrives via text message
5. Confirm, and your verified phone number is added to your wallet

The same simple flow applies to email addresses—just check your inbox for the verification code instead.

The new Yivi app UX flow for issuing your phone number

Still works during disclosure​

If a service requests your phone number and you haven't added it yet, Yivi already lets you issue missing credentials on the spot. That hasn't changed—but now you won't be redirected to a website to complete the process. Everything stays inside the app, so the flow feels uninterrupted.

Inspired by what worked​

You may have noticed that Yivi recently added the ability to issue passports, ID cards, and driving licences directly in the app. That feature proved how much smoother the experience becomes when you don't have to jump between websites and your wallet. We took that lesson and applied it here. Phone numbers and email addresses are some of the most commonly requested credentials, so bringing them into the same seamless in-app flow felt like a natural next step. User experience remains one of our primary focuses for Yivi. Every tap we can eliminate, every context switch we can remove, brings us closer to an identity wallet that simply works.

Try it now​

This feature is currently in beta and will be available to all users soon. If you're already using Yivi, keep an eye out for the update—and let us know what you think.

We're building Yivi for you, and your feedback helps us make it better.

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.

A few months ago, we announced our plans to become an EUDI wallet while still retaining our original privacy-by-design technology.

Since that announcement, we've come a long way, and today it's time to announce the release of the first major step towards true crypto agility: the support for the OpenID4VP protocol and the SD-JWT VC credential format in the Yivi app. In this blog, we'll dive into how we did this and what it means for you.

We are announcing the release of the Trusted Verifier on the 24th of September!

Trusted Verifiers marks a crucial step forward in our mission to enhance the security and reliability of digital identity verification within the Yivi ecosystem. It also secures the long term sustainability of the Yivi project.

We are excited to announce the BETA release of Yivi Passport credentials!
This new feature allows users to securely store and manage their digital passports within the Yivi wallet, enhancing convenience and accessibility for travelers. With this release, Yivi expands its reach to a truly international audience.

Our mission is to make Yivi the most privacy and user friendly wallet out there. In line with this mission we developed our crypto agile vision, allowing users to use different cryptographic technologies in a seamless way. As part of this vision, we want to support verifiable credentials, which are becoming increasingly popular in the digital identity space.

Yivi Portal is Yivi's new initiative to help with a smooth launch for the Trusted/Pretty verifier. Trusted Verifier is a pivotal part of the roadmap as mentioned in earlier blog posts and serves as part of our commitment to our users, as well as helps with transparency with our verifiers in covering the downstream costs of various verification sessions that our issuers bear.

In this blog post I will dive into what the portal exactly is, and what can you expect from the coming updates.
