EUDI Wallet data sharing user flows are designed by defining identification and authorization journeys, applying ARF specifications for remote and proximity-based sharing to ensure secure PID and attestation data transfer. This guidance covers the full user journey from request to successful delivery.

EUDI Wallet user identification supports PIN, biometrics, and OTP authentication methods. You should compare these options based on your specific security requirements and user flow context, balancing convenience against the necessary assurance levels for sharing PID with relying parties.

Selective disclosure for PID sharing in EUDI Wallet applications works by implementing user control mechanisms that ensure transparency and explicit consent before data transmission. This allows users to share only the specific attestation data requested by the relying party rather than their full digital ID.

Handling errors for invalid EUDI Wallet credentials or untrusted relying parties involves managing and displaying specific error states within the user flow. You must design clear UI responses for credential failures, invalid documents, and untrusted relying party requests to maintain security and guide users.

You need ARF specifications for designing EUDI Wallet data sharing features whenever your application requires users to share PID or attestation data with government services or other relying parties. ARF provides the foundational rules for secure identification and authorization flows.

EUDI Wallet flow guidance applies to both government services and private relying parties. The design principles for identification, authorization, and user control mechanisms cover the secure sharing of digital ID and attestation data across various service providers.
