iGrant.io Authenticator credential schema
When to use
Use this skill when you issue or ask for an iGrant.io Authenticator credential. The credential proves control of one email address, and nothing else. It is the smallest schema in the registry: one claim. iGrant.io uses it for passwordless sign-in, where the user presents the credential in place of a password.
The registry publishes this schema in all three formats:
| Format | Metadata flag | Identifier to send |
|---|---|---|
dc+sd-jwt |
isSdJwt: true |
vct |
jwt_vc_json |
isJwt: true |
type |
mso_mdoc |
isMsoMdoc: true |
doctype |
This page describes registry version 2025.7.1, the latest version of the template.
