Deactivate ``findface-liveness-api`` installed with FindFace Multi
=======================================================================

If you don't utilize the ``findface-liveness-api`` service installed with FindFace Multi and the face-based authentication does not apply to your system, we recommend deactivating ``findface-liveness-api``. 

Do the following:

#. Stop the ``findface-liveness-api`` service and disable its autostart by executing:

   .. code::
 
      sudo systemctl stop findface-liveness-api.service && sudo systemctl disable findface-liveness-api.service

#. Open the ``/etc/findface-extraction-api.ini`` configuration file.

      .. code::
   
         sudo vi /etc/findface-extraction-api.ini

#. Disable the neural network model used by the ``findface-liveness-api`` service. To do so, pass the empty value ``''`` to the ``face_liveness`` parameter. 

   .. note::
      Do not remove the parameter itself. Otherwise, the system will be searching for the default model. 

   .. code::

      extractors:
        models:
          ...
          face_liveness: ''
          ...

#. Restart ``findface-extraction-api``.

      .. code::

         sudo systemctl restart findface-extraction-api
