FAQPage Schema
What is the OpenID4VCI specification for verifiable credentials?▼

OpenID4VCI is a specification defining how digital wallets request and receive verifiable credentials from a Credential Issuer. It standardizes credential issuance flows to ensure secure digital identity integration.

How does OpenID4VCI relate to OAuth 2.0?▼

OpenID4VCI builds upon OAuth 2.0 to manage credential issuance. It adapts OAuth 2.0 authorization mechanisms, utilizing authorization code and pre-authorized code flows to securely issue verifiable credentials to a digital wallet.

What is the pre-authorized code flow in OpenID4VCI?▼

The pre-authorized code flow is an OpenID4VCI process where the Credential Issuer pre-authorizes a credential request. It allows a Wallet to retrieve verifiable credentials without standard interactive user authorization at issuance time.

How do I integrate a digital wallet with a credential issuer?▼

You integrate a digital wallet with a Credential Issuer by implementing the OpenID4VCI specification. This involves configuring the Wallet to handle the authorization code flow to successfully retrieve verifiable credentials.

What are the key components involved in OpenID4VCI credential issuance?▼

Key OpenID4VCI components include the Credential Issuer, which dispenses credentials, and the Wallet, which stores them. They interact via OAuth 2.0 authorization code or pre-authorized code flows for secure credential issuance.
