+Authentication
+**************
+
+.. _Overview:
+
+Overview
+========
+
+*   **If you're running in Compute Engine or App Engine**,
+    authentication should "just work".
+
+*   **If you're developing locally**,
+    the easiest way to authenticate is using the `Google Cloud SDK`_:
+
+    .. code-block:: bash
+
+        $ gcloud auth application-default login
+
+    Note that this command generates credentials for client libraries. To authenticate the CLI itself, use:
+
+    .. code-block:: bash
+
+        $ gcloud auth login
+
+    Previously, ``gcloud auth login`` was used for both use cases. If
+    your ``gcloud`` installation does not support the new command,
+    please update it:
+
+    .. code-block:: bash
+
+        $ gcloud components update
+
+.. _Google Cloud SDK: http://cloud.google.com/sdk
+
+
+*   **If you're running your application elsewhere**,
+    you should download a `service account`_ JSON keyfile
+    and point to it using an environment variable:
+
+    .. code-block:: bash
+
+        $ export GOOGLE_APPLICATION_CREDENTIALS="/path/to/keyfile.json"
+
+.. _service account: https://cloud.google.com/storage/docs/authentication#generating-a-private-key
+
+Client-Provided Authentication
+==============================
+
+Every package uses a :class:`Client <google.cloud.client.Client>`
+as a base for interacting with an API.
+For example:
+
+.. code-block:: python
+
+    from google.cloud import datastore
+    client = datastore.Client()
+
+Passing no arguments at all will "just work" if you've followed the
+instructions in the :ref:`Overview`.
+The credentials are inferred from your local environment by using
+Google `Application Default Credentials`_.
+
+.. _Application Default Credentials: https://developers.google.com/identity/protocols/application-default-credentials
+
+.. _Precedence:
+
+Credential Discovery Precedence
+-------------------------------
+
+When loading the `Application Default Credentials`_,
+the library will check for credentials in your environment by following the
+precedence outlined by :func:`google.auth.default`.
+
+Explicit Credentials
+====================
+
+The Application Default Credentials discussed above can be useful
+if your code needs to run in many different environments or
+if you just don't want authentication to be a focus in your code.
+
+However, you may want to be explicit because
+
+* your code will only run in one place
+* you may have code which needs to be run as a specific service account
+  every time (rather than with the locally inferred credentials)
+* you may want to use two separate accounts to simultaneously access data
+  from different projects
+
+In these situations, you can create an explicit
+:class:`~google.auth.credentials.Credentials` object suited to your environment.
+After creation, you can pass it directly to a :class:`Client <google.cloud.client.Client>`:
+
+.. code:: python
+
+    client = Client(credentials=credentials)
+
+.. tip::
+    To create a credentials object, follow the `google-auth-guide`_.
+
+.. _google-auth-guide: https://google-auth.readthedocs.io/en/latest/user-guide.html#service-account-private-key-files
+
+
+Google App Engine Environment
+-----------------------------
+
+To create
+:class:`credentials <google.auth.app_engine.Credentials>`
+just for Google App Engine:
+
+.. code:: python
+
+    from google.auth import app_engine
+    credentials = app_engine.Credentials()
+
+Google Compute Engine Environment
+---------------------------------
+
+To create
+:class:`credentials <google.auth.compute_engine.Credentials>`
+just for Google Compute Engine:
+
+.. code:: python
+
+    from google.auth import compute_engine
+    credentials = compute_engine.Credentials()
+
+Service Accounts
+----------------
+
+A `service account`_ is stored in a JSON keyfile.
+
+The
+:meth:`from_service_account_json() <google.cloud.client.Client.from_service_account_json>`
+factory can be used to create a :class:`Client <google.cloud.client.Client>` with
+service account credentials.
+
+For example, with a JSON keyfile:
+
+.. code:: python
+
+    client = Client.from_service_account_json('/path/to/keyfile.json')
+
+.. tip::
+
+    Previously the Google Cloud Console would issue a PKCS12/P12 key for your
+    service account. This library does not support that key format. You can
+    generate a new JSON key for the same service account from the console.
+
+User Accounts (3-legged OAuth 2.0) with a refresh token
+-------------------------------------------------------
+
+The majority of cases are intended to authenticate machines or
+workers rather than actual user accounts. However, it's also
+possible to call Google Cloud APIs with a user account via
+`OAuth 2.0`_.
+
+.. _OAuth 2.0: https://developers.google.com/identity/protocols/OAuth2
+
+.. tip::
+
+    A production application should **use a service account**,
+    but you may wish to use your own personal user account when first
+    getting started with the ``google-cloud-python`` library.
+
+The simplest way to use credentials from a user account is via
+Application Default Credentials using ``gcloud auth login``
+(as mentioned above) and :func:`google.auth.default`:
+
+.. code:: python
+
+    import google.auth
+
+    credentials, project = google.auth.default()
+
+This will still follow the :ref:`precedence <Precedence>`
+described above,
+so be sure none of the other possible environments conflict
+with your user provided credentials.
+
+Advanced users of `oauth2client`_ can also use custom flows to
+create credentials using `client secrets`_ or using a
+`webserver flow`_.
+After creation, :class:`Credentials <oauth2client.client.Credentials>`
+can be serialized with
+:meth:`to_json() <oauth2client.client.Credentials.to_json>`
+and stored in a file and then and deserialized with
+:meth:`from_json() <oauth2client.client.Credentials.from_json>`. In order
+to use ``oauth2client``'s credentials with this library, you'll need to
+`convert them`_.
+
+.. _oauth2client: https://github.com/Google/oauth2client.
+.. _client secrets: https://developers.google.com/api-client-library/python/guide/aaa_oauth#flow_from_clientsecrets
+.. _webserver flow: https://developers.google.com/api-client-library/python/guide/aaa_oauth#OAuth2WebServerFlow
+.. _convert them: http://google-auth.readthedocs.io/en/stable/user-guide.html#user-credentials
+
+Troubleshooting
+===============
+
+Setting up a Service Account
+----------------------------
+
+If your application is not running on Google Compute Engine,
+you need a `Google Developers Service Account`_.
+
+#. Visit the `Google Developers Console`_.
+
+#. Create a new project or click on an existing project.
+
+#. Navigate to **APIs & auth** > **APIs** and enable the APIs
+   that your application requires.
+
+   .. raw:: html
+
+     <img src="https://raw.githubusercontent.com/GoogleCloudPlatform/google-cloud-common/master/authentication/enable-apis.png"/>
+
+  .. note::
+
+      You may need to enable billing in order to use these services.
+
+      * **BigQuery**
+
+        * BigQuery API
+
+      * **Datastore**
+
+        * Google Cloud Datastore API
+
+      * **Pub/Sub**
+
+        * Google Cloud Pub/Sub
+
+      * **Storage**
+
+        * Google Cloud Storage
+        * Google Cloud Storage JSON API
+
+#. Navigate to **APIs & auth** > **Credentials**.
+
+   You should see a screen like one of the following:
+
+   .. raw:: html
+
+     <img src="https://raw.githubusercontent.com/GoogleCloudPlatform/google-cloud-common/master/authentication/create-new-service-account.png">
+
+   .. raw:: html
+
+     <img src="https://raw.githubusercontent.com/GoogleCloudPlatform/google-cloud-common/master/authentication/create-new-service-account-existing-keys.png">
+
+  Find the "Add credentials" drop down and select "Service account" to be
+  guided through downloading a new JSON keyfile.
+
+  If you want to re-use an existing service account,
+  you can easily generate a new keyfile.
+  Just select the account you wish to re-use,
+  and click **Generate new JSON key**:
+
+   .. raw:: html
+
+     <img src="https://raw.githubusercontent.com/GoogleCloudPlatform/google-cloud-common/master/authentication/reuse-service-account.png">
+
+.. _Google Developers Console: https://console.developers.google.com/project
+.. _Google Developers Service Account: https://developers.google.com/accounts/docs/OAuth2ServiceAccount
+
+Using Google Compute Engine
+---------------------------
+
+If your code is running on Google Compute Engine,
+using the inferred Google `Application Default Credentials`_
+will be sufficient for retrieving credentials.
+
+However, by default your credentials may not grant you
+access to the services you intend to use.
+Be sure when you `set up the GCE instance`_,
+you add the correct scopes for the APIs you want to access:
+
+* **All APIs**
+
+    * ``https://www.googleapis.com/auth/cloud-platform``
+    * ``https://www.googleapis.com/auth/cloud-platform.read-only``
+
+* **BigQuery**
+
+    * ``https://www.googleapis.com/auth/bigquery``
+    * ``https://www.googleapis.com/auth/bigquery.insertdata``
+
+* **Datastore**
+
+    * ``https://www.googleapis.com/auth/datastore``
+    * ``https://www.googleapis.com/auth/userinfo.email``
+
+* **Pub/Sub**
+
+    * ``https://www.googleapis.com/auth/pubsub``
+
+* **Storage**
+
+    * ``https://www.googleapis.com/auth/devstorage.full_control``
+    * ``https://www.googleapis.com/auth/devstorage.read_only``
+    * ``https://www.googleapis.com/auth/devstorage.read_write``
