Single sign-on (SSO)
Admin only
Single sign-on lets your organization's people sign in to Nomain with the same corporate identity they already use: Okta, Microsoft Entra ID, Auth0, Keycloak, and others. Instead of managing separate Nomain passwords, your users authenticate through your existing identity provider.
A tenant administrator sets this up directly from the Account screen, in a guided flow, with no support ticket and no waiting on Nomain staff.
Setting up SSO
- Open the Account screen from the user menu. In the Organization section, administrators see a Single Sign-On (SSO) card ("Connect your identity provider (Okta, Entra ID, Auth0…)").
- Click Configure SSO.
- A Configure Single Sign-On confirmation dialog appears. It explains that this opens the WorkOS configuration portal and that changes affect all users in your organization. Proceed only if you administer your identity provider.
- Click Continue to WorkOS.
- You are redirected to a secure, hosted configuration portal, where you connect and validate your identity provider by following its guided steps.
- Return to the Account screen. The SSO card reflects the updated connection status.


Connection status
The SSO card shows the current state of your connection:
| Status | Meaning |
|---|---|
| Not configured | No connection has been set up yet. |
| Active · via <provider> | SSO is live; users sign in through your provider. |
| Pending: finish setup | Setup was started but is not yet complete. A new connection may stay pending until the first successful sign-in through your provider. |
| Disabled | A connection exists but is currently inactive. |
Good to know
Reconfiguring can interrupt sign-in
Editing an existing connection can interrupt sign-in for everyone in your organization, and the connection may stay Pending until the next successful sign-in. Change it during a maintenance window if you can, and make sure you have your identity provider's details ready.
- Self-serve. No support ticket is required. You launch the guided portal yourself.
- Organization-wide. SSO settings apply to every user in your organization, not just to the admin making the change.
- Named providers. The interface names Okta, Entra ID, Auth0 and Keycloak. The underlying identity platform (WorkOS AuthKit) supports additional SAML and OIDC providers beyond these examples.
- Admin only. The SSO card is visible only to administrators, and the setup endpoints are enforced server-side.
