What is OpenID4VC (OpenID for Verifiable Credentials)?

OpenID4VC (OpenID for Verifiable Credentials) is an authentication protocol that extends the OpenID Connect standard, allowing users to securely request, obtain, and manage cryptographically verifiable credentials from trusted issuers. These credentials confirm identity attributes digitally, eliminating reliance on traditional usernames and passwords.

OpenID4VC facilitates:

• Secure Issuance of Credentials: Users securely obtain digital credentials from trusted entities (e.g., banks, governments, educational institutions).
• User-Controlled Identity: Users manage credentials securely in personal digital wallets, maintaining full control over their identity information.
• Cryptographic Verification: Credentials are cryptographically verifiable, ensuring data integrity and authenticity.
• Privacy-Preserving Authentication: Users selectively share credential details, ensuring minimal disclosure of personal information.

OpenID4VC supports decentralized identity models, making it pivotal for secure, user-centric digital identity ecosystems.

OpenID4VC (OpenID for Verifiable Credentials) extends the widely adopted OpenID Connect standard to support secure and decentralized digital identity solutions. Leveraging cryptographic techniques, OpenID4VC offers an advanced method for digital identity verification, significantly improving privacy, security, and user experience.

The OpenID4VC workflow typically involves three primary participants:

1. Issuer: The issuer is an authoritative organization (e.g., government agency, financial institution, university) that creates and issues verifiable credentials containing digitally signed identity attributes.

2. Holder (User): The user stores their verifiable credentials securely in a personal digital wallet (typically on a smartphone or computer), maintaining full control over credential usage and sharing.

3. Verifier (Relying Party): When accessing a service, the user selectively presents requested credentials. The verifier cryptographically validates these credentials without contacting the original issuer, thus ensuring the authenticity and integrity of the presented data.

• Enhanced Privacy and User Control: Users decide exactly which personal details they share, greatly reducing unnecessary data exposure and enhancing compliance with data protection regulations (e.g., GDPR).

• Improved Security: By leveraging cryptographic signatures and verifiable credentials, OpenID4VC significantly mitigates identity theft, phishing, and credential compromise.

• Passwordless Authentication: OpenID4VC promotes seamless, frictionless authentication experiences, eliminating cumbersome passwords and their inherent security risks.

• Support for Decentralized Identity (DID): OpenID4VC aligns closely with decentralized identity approaches, empowering users to manage their digital identities independently from central authorities.

OpenID4VC has significant applications across various sectors:

• Finance and Banking: Enables secure, privacy-preserving onboarding processes, reducing fraud risks and compliance burdens associated with identity verification.

• Healthcare: Facilitates secure access to electronic medical records, telemedicine services, and prescriptions, ensuring patient privacy and regulatory compliance.

• E-Government Services: Streamlines secure access to governmental services, reducing bureaucracy and increasing citizen convenience and trust.

• Education: Simplifies verification of academic credentials, certificates, and diplomas, significantly reducing administrative overhead.

OpenID4VC naturally complements modern authentication methods like passkeys (WebAuthn/FIDO2). Combining verifiable credentials with phishing-resistant, passwordless authentication creates a robust digital identity management framework. This approach dramatically strengthens security and improves user experience in digital interactions.

In summary, OpenID4VC represents a significant step forward in digital identity management, offering secure, decentralized, and privacy-centric solutions for modern authentication needs.

OpenID4VC (OpenID for Verifiable Credentials) is an extension of OpenID Connect, allowing secure issuance and cryptographic verification of digital identity credentials, enhancing security and privacy.

OpenID4VC enables users to selectively disclose only necessary credential attributes, significantly enhancing user privacy and control over personal information.

A verifiable credential is a cryptographically secured digital document issued by trusted entities, confirming specific attributes of a user’s identity (e.g., age, nationality, qualifications).

Yes, OpenID4VC fully supports decentralized identity models, allowing users independent management of their credentials without relying on centralized authorities.

OpenID4VC integrates seamlessly with passkeys, providing secure, phishing-resistant, and frictionless authentication experiences, significantly improving security and usability.
