# Credential Schemas
### Introduction
Credential schemas define the contents and structure of a set of claims in a verifiable credential. Within the SVX Portal they are used by Organisation Administrators when issuing and verifying credentials. See Issue / Revoke Credentials and Verification Templates for more information. It is the responsibility of the Tenant Administrator to create and manage credential schemas, and assign them to Organisations within their Tenancy.

Tenant Administrators can create new credential schemas by navigating to *Credentials* on the left-side menu of the SVX Portal, and selecting *Credential schemas*. After selecting the *Create credential schema* button, you will be presented with a form. The form consists of the following fields:
