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-multi-findface-liveness-api-1`` container and disable its autostart by executing:

   .. code::
 
      sudo docker container stop findface-multi-findface-liveness-api-1
      sudo docker update --restart=no findface-multi-findface-liveness-api-1

#. Open the ``/opt/findface-multi/configs/findface-extraction-api/findface-extraction-api.yaml`` configuration file.

   .. code::
   
      sudo vi /opt/findface-multi/configs/findface-extraction-api/findface-extraction-api.yaml

#. Disable the neural network models used by the ``findface-liveness-api`` service. To do so, pass the empty value ``''`` to the ``multicrop_full_crop2x`` and ``face_liveness`` parameters. 

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

   .. code::

      normalizers:
        models:
          ...
          multicrop_full_crop2x: ''
          ...
         
      extractors:
        models:
          ...
          face_liveness: ''
          ...

#. Restart the ``findface-multi-findface-extraction-api-1`` container.

   .. code::

      sudo docker container restart findface-multi-findface-extraction-api-1
