The integration is free. ## Setting up OpenID 1. In your identity provider, create an application for Nexudus. Add the **Redirect URI** shown in Nexudus (in **Settings → Integrations → OpenId**) as an allowed callback URL. 2. Copy the provider's **Authority URL**, **Log out URL**, **Client ID** and **Client Secret** — you'll find them in its admin dashboard. In Auth0, they're in your application's settings. 3. In **Settings → Integrations → OpenId**, turn on **Enable OpenId integration.** and enter those details. 4. Set a **Sign in button label**, choose the [shared SSO options](/integrations/sso#options-every-sso-integration-shares), and save. OpenID settings Test by signing in as both a customer and an admin. The settings also show a **Login URI** — a direct link that signs people in through your provider. ## Related * [Single sign-on](/integrations/sso) — shared SSO options This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
