Configure Auth0 OIDC SSO

Learn how to set up Auth0 SSO with OpenID Connect (OIDC).

Available on:Enterprise plan

Use this guide to configure Auth0 SSO with OpenID Connect (OIDC) on Retool. Once configured, users can log in to Retool with their Auth0 credentials.


To configure Auth0 SSO, you must:

  • Have admin permissions on Retool Cloud or permissions to add environment variables on self-hosted Retool instances.
  • Have permissions to create an OIDC application in Auth0.

1. Create a new Auth0 application

In Auth0, create a new application for Retool. Go to your application Settings and save the Client ID and Client secret.

Next, save the OAuth Authorization URL and OAuth Token URL. In Auth0, this is found in Settings > Advanced Settings > Endpoints.

Add https://<subdomain> as the callback URL, replacing <subdomain> with your subdomain. In Auth0, the callback URL is set in Settings > Application URIs.

2. Configure settings in Retool

Configure your SSO settings in Retool.


When possible, use the Settings UI to configure SSO for a more streamlined setup. Existing environment variables pre-populate in the Settings UI, which you can override or preserve. Some settings are only available as environment variables.

On Retool Cloud and self-hosted Retool versions 3.16 and later, enter settings on Settings > Single Sign-On (SSO).

Optional settings

To provide authorization to access resources when a user logs in with SSO, specify the API audience that corresponds to the resource as configured in Auth0. Find the API audience in the Auth0 UI under Applications > APIs. Set this value as the CUSTOM_OAUTH2_SSO_AUDIENCE environment variable in your Retool deployment, or in the SSO Audience field in the Retool UI.


If you don't configure the CUSTOM_OAUTH2_SSO_AUDIENCE setting, Retool receives an opaque token, and you won't be able to use the accessToken to control access to components and resources.

3. Save your settings

If you use the settings page for configuration, save your settings. You can test out your configuration by logging in from an incognito window.

If you added environment variables, restart your Retool instance.
