auth0 provides authentication for the majority of 2i2c hubs. It can be configured with many different connections that users can authenticate with - such as Google, GitHub, etc.


If you wish to authenticate users based on their membership in a GitHub organization or team, you’ll need to use the native GitHub OAuthenticator instead.

So we want to manage authentication by:

  1. Explicitly listing the type of connection we want for this hub, via auth0.connection. Currently common ones are google-oauth2 for Google & github for GitHub. Users of the hub will use this method to log in to the hub.

    You can set the auth0 connector for a hub with:

       connection: google-oauth2

    Theoretically, every provider in this list is supported. However, we’ve currently only tested this with Google (google-oauth2) and GitHub (github)

  2. Explicitly list admin users for a given hub. These admin users will be the only ones allowed to log in to begin with. They can use the JupyterHub admin interface (available from their hub control panel) to explicitly allow more users into the hub. This way, we don’t need to be involved in explicitly allowing users into hubs.

    In the admin interface, admin users can add users via a username appropriate for the auth connector used. For GitHub, it’s the username. For Google Auth, it’s the email address.

    You can set the admin interfaces for a hub like this:

            # WARNING: THESE USER LISTS MUST MATCH (for now)
            # WARNING: THESE USER LISTS MUST MATCH (for now)
