OIDC Single Sign-On guide

DigiCert allows customers to connect CertCentral to a federated identity provider using Open ID Connect (OIDC), so that users who have accounts on the customer’s network can use their existing SSO credentials.

Users who connect through SAML do not need to switch, but many customers prefer OIDC for ease of implementation.

Instead of adding someone to your account just to order a client certificate, send them your OIDC Certificate Requests URL. Once authenticated, they have access to their own account where they can request and manage their client certificate (by checking their order status, downloading a copy of their certificate, and other ways).
