OpenID4VCI
Also known as: OpenID for Verifiable Credential Issuance
An OpenID Foundation spec that standardizes how a wallet holder pulls a verifiable credential from an issuer via OAuth-style flows.
OpenID for Verifiable Credential Issuance (OpenID4VCI) is a draft specification from the OpenID Foundation that defines how a wallet obtains a verifiable credential from an issuer. It reuses the familiar OAuth 2.0 flow: the wallet authenticates, receives an authorization grant, and redeems the grant for a credential offer.
OpenID4VCI is the EU's mandated issuance path under eIDAS 2.0 — every EUDI Wallet is expected to support it. It's also gaining traction outside the EU as the canonical wallet-to-issuer protocol. The sibling spec OpenID4VP (Verifiable Presentations) covers the wallet-to-verifier path.
LearnCoin does not implement OpenID4VCI today. It's on the 2026-2027 roadmap as part of the broader EUDI ARF alignment track. Today, LearnCoin's credential-delivery path is a magic-link claim flow (the tenant issues the credential via the API, LearnCoin emails the recipient a one-time link to claim it).
