===================================
Authenticate using GitHub Usernames
===================================
The **GitHub Authenticator** lets users log into your JupyterHub using their
GitHub user ID / password. To do so, you'll first need to register an
application with GitHub, and then provide information about this
application to your ``tljh`` configuration.
Enabling the authenticator
==========================
.. note::
You'll need a GitHub account in order to complete these steps.
#. Create a GitHub application
#. Go to the `GitHub OAuth app creation page <https://github.com/settings/applications/new>`_.
#. **Application name**: Choose a descriptive application name (e.g. ``tljh``)
#. **Homepage URL**: Use the IP address or URL of your JupyterHub. e.g. ``http://<my-tljh-url>```.
#. **Application description**: Use any description that you like.
#. **Authorization callback URL**: Insert text with the following form::
http://<my-tljh-url>/hub/oauth_callback
#. When you're done filling in the page, it should look something like this:

:alt: Create a GitHub OAuth application
#. Click "Register application".
#. You'll be taken to a page with the registered application details. Note
the **Client ID** and **Client Secret**, as you will use these later.

#. Configure your JupyterHub to use the GitHub Oathenticator
#. Log in as an administrator account to your JupyterHub.
#. Open a terminal on your JupyterHub.
#. Configure the GitHub OAuthenticator to use your client ID and secret with the following commands::
sudo -E tljh-config set auth.GitHubOAuthenticator.client_id '<my-tljh-client-id>'
sudo -E tljh-config set auth.GitHubOAuthenticator.client_secret '<my-tljh-client-secret>'
#. Tell your JupyterHub to *use* the GitHub OAuthenticator for authentication::
sudo -E tljh-config set auth.type oauthenticator.github.GitHubOAuthenticator
#. Restart your JupyterHub so that new users see these changes::
sudo -E tljh-config reload
#. Confirm that the new authentactor works.
#. Open an **incognito window** in your browser.
#. Go to your JupyterHub URL.
#. You should see a GitHub login button like below:
