Yivi

Yivi is a mobile ID wallet that lets you securely log in, share data and prove your identity while minimizing what you reveal. You always see what an organization requests and decide which attributes to share. All credentials and data are stored locally on your phone, protected by a PIN — not on a central server — so no one (not even Yivi) can view your information.

Built by the Caesar Groep and based on work from the Privacy By Design Foundation (formerly IRMA), Yivi is fully open-source and designed around privacy-by-design principles. It supports selective disclosure and verifiable credentials, with technical docs and source code available for developers and auditors at docs.yivi.app and github.com/privacybydesign. Ideal for users and organizations seeking user-controlled, transparent digital identity and secure authentication.
