<title>Authenticate</title>
<para>When using the SDK, you must authenticate against an OpenStack
endpoint before you can use OpenStack services. Each project uses
a slightly different syntax for authentication.</para>
<para>You must typically authenticate against a specific version of
a service. For example, a client might need to authenticate
against Identity v2.0.</para>
<para>Python scripts that use the OpenStack SDK must have access to the
credentials contained in the
<link linkend="cli_openrc">OpenStack RC file</link>. Because credentials
are sensitive information, do not include them in your scripts. This guide
assumes that users source the
<filename><replaceable>PROJECT</replaceable>-openrc.sh</filename>
file and access the credentials by using the environment variables
in the Python scripts.</para>
