+Enabling Authentication
+=======================
+
+By default BinderHub runs without authentication and
+for each launch it creates a temporary user and starts a server for that user.
+
+In order to enable authentication for BinderHub by using JupyterHub as an oauth provider,
+you need to add the following into ``config.yaml``:
+
+.. code:: yaml
+
+    config:
+      BinderHub:
+        auth_enabled: true
+
+    jupyterhub:
+      cull:
+        # don't cull authenticated users
+        users: False
+
+      hub:
+        services:
+          binder:
+            oauth_redirect_uri: "<binderhub_url>/oauth_callback"
+            oauth_client_id: "binder-oauth-client-test"
+        extraConfig:
+          binder: |
+            from kubespawner import KubeSpawner
+
+            class BinderSpawner(KubeSpawner):
+              def start(self):
+                  if 'image' in self.user_options:
+                    # binder service sets the image spec via user options
+                    self.image_spec = self.user_options['image']
+                  return super().start()
+            c.JupyterHub.spawner_class = BinderSpawner
+
+      singleuser:
+        # to make notebook servers aware of hub
+        cmd: jupyterhub-singleuser
+
+      auth: {}
+
+.. note::
+    For `jupyterhub.auth` you should use config of your authenticator.
+    For more information you can check
+    `the Authentication guide
+    <https://zero-to-jupyterhub.readthedocs.io/en/stable/authentication.html>`_.
+
+.. warning::
+    `jupyterhub-singleuser` requires `JupyterHub` to be installed in user server images.
+    Therefore ensure that you use at least `jupyter/repo2docker:ccce3fe` image
+    to build user images. Because `repo2docker` installs `JupyterHub` by default after that.
+
+Authentication with named servers
+---------------------------------
+
+With above configuration Binderhub limits each authenticated user to start one server at a time.
+When a user already has a running server, BinderHub displays an error message.
+
+If you want to have users be able to launch multiple servers at the same time,
+you have to enable named servers on JupyterHub:
+
+.. code:: yaml
+
+    config:
+      BinderHub:
+        use_named_servers: true
+    jupyterhub:
+      hub:
+        allowNamedServers: true
+
+.. note::
+    BinderHub assigns a unique name to each server with max 40 characters.
