Auth0

This page documents configuring an Auth0 Web Application and Machine to Machine Application for Pomerium to read user data. It assumes you have already installed Pomerium.

caution

While we do our best to keep our documentation up to date, changes to third-party systems are outside our control. Refer to Applications in Auth0 from Auth0's docs as needed, or let us know if we need to re-visit this page.

Log in to your Auth0 account and head to your dashboard. Select Applications → Applications on the left menu. On the Applications page, click the Create Application button to create a new app.

Auth0 Applications Dashboard

Create Regular Web Application​

  1. On the Create New Application page, name your application and select the Regular Web Application for your application. This is the application that your users will login to.

    Auth0 Create Application Select Platform

  2. Under the Settings tab, note the Domain, Client ID, and Client Secret values. We'll provide these to Pomerium at the end of the process.

  3. Provide the following information for your application settings:

    FieldDescription
    NameThe name of your application.
    Application Login URIAuthenticate Service URL (e.g. https://${authenticate_service_url})
    Allowed Callback URLsRedirect URL (e.g. https://${authenticate_service_url}/oauth2/callback).

  4. Under Advanced Settings → OAuth, confirm that JSON Web Token (JWT) Signature Algorithm is set to "RS256".

  5. Click Save Changes at the bottom of the page when you're done.

Service Account​

Next, we'll create an application to handle machine-to-machine communication from Pomerium to Auth0 in order to retrieve and establish group membership.

tip

Auth0 refers to groups as roles.

  1. Repeat the process in step 1 above to create a new application, but this time select Machine to Machine Application. A different application is used for grabbing roles to keep things more secure.

    Auth Create Application Select Service Account Platform

    Click Create.

  2. On the next page select Auth0 Management API from the dropdown. Under Permissions use the filter on the right to narrow things down to role, and choose the read:roles and read:role_members roles.

    Then click Authorize.

  3. Just like the previous step, retrieve the Client ID and Client Secret from the Settings tab. To build the idp_service_account value for Pomerium's configuration, you must base64-encode a JSON document containing the Client ID and Client Secret of the application:

    {
    "client_id": "...",
    "secret": "..."
    }

    If you save this JSON document as a temporary file, you can encode it like this:

    cat json.tmp | base64 -w 0

Configure Pomerium​

You can now configure Pomerium with the identity provider settings retrieved in the previous steps. Your config.yaml keys or environmental variables should look something like this.

idp_provider: "auth0"
idp_provider_url: "https://awesome-company.auth0.com"
idp_client_id: "REPLACE_ME" # from the web application
idp_client_secret: "REPLACE_ME" # from the web application
idp_service_acount: "REPLACE_ME" # built from the machine-to-machine application, base64-encoded
tip

Remember to prepend the provider URL from Auth0 with https://.
