- class Qctrl(email=None, password=None, api_root=None, oidc_url=None, env_namespace=None, skip_version_check=False, client=None, verbosity='VERBOSE', organization=None)
A mediator class. Used to authenticate with Q-CTRL and access Q-CTRL features.
Creating an instance of this class requires authentication with Q-CTRL’s API.
The recommended method of authentication is through the interactive authentication method. This method can be invoked by simply calling Qctrl() without any arguments. This method will also create an authentication file that will be used for subsequent authentications when using the package.
qctrl = Qctrl()
You can also access toolkits provided by Boulder Opal through the corresponding namespaces of the Qctrl object. See the reference for details.
Deprecated since version 15.4.4: Email and password based authentication has been removed in favour of url based authentication. To authenticate simply call qctrl = Qctrl() without any additional arguments.
