Verifiable Credentials

ThunderID implements the OpenID for Verifiable Credentials family of specifications, both issuance and presentation, allowing you to issue digital identity credentials to wallets and accept cryptographic proof of those credentials at relying parties.

Verifiable credentials complement the OAuth 2.1 and OpenID Connect stack: instead of prompting for a username and password, the relying party requests cryptographic proof from an existing government- or institution-issued credential.

For other identity standards, see the Protocols & Standards overview.
