Keycloak OIDC SSO is a paid feature. If you’re using Infisical Cloud, then it is available under the Pro Tier. If you’re self-hosting Infisical, then you should contact sales@infisical.com to purchase an enterprise license to use it.

Create an OIDC client application in Keycloak

1.1. In your realm, navigate to the Clients tab and click Create client to create a new client application.

You don’t typically need to make a realm dedicated to Infisical. We recommend adding Infisical as a client to your primary realm.

1.2. In the General Settings step, set Client type to OpenID Connect, the Client ID field to an appropriate identifier, and the Name field to a friendly name like Infisical.

Enable OIDC SSO in Infisical

Enabling OIDC SSO allows members in your organization to log into Infisical via Keycloak.

5

Enforce OIDC SSO in Infisical

Enforcing OIDC SSO ensures that members in your organization can only access Infisical by logging into the organization via Keycloak.

To enforce OIDC SSO, you’re required to test out the OpenID connection by successfully authenticating at least one Keycloak user with Infisical. Once you’ve completed this requirement, you can toggle the Enforce OIDC SSO button to enforce OIDC SSO.

We recommend ensuring that your account is provisioned using the application in Keycloak prior to enforcing OIDC SSO to prevent any unintended issues.

If you are only using one organization on your Infisical instance, you can configure a default organization in the Server Admin Console to expedite OIDC login.

If you’re configuring OIDC SSO on a self-hosted instance of Infisical, make sure to set the AUTH_SECRET and SITE_URL environment variable for it to work:

  • AUTH_SECRET: A secret key used for signing and verifying JWT. This can be a random 32-byte base64 string generated with openssl rand -base64 32.
  • SITE_URL: The absolute URL of your self-hosted instance of Infisical including the protocol (e.g. https://app.infisical.com)
