# Authentication username for writing to index

If your Elasticsearch server requires a different HTTP basic authentication username and password to write to index, you may provide the indexingusername here. Note: The core Elasticsearch software itself does not provide username or password features, but you may achieve this functionality by using a plugin, such as Search Guard, or by accessing it through a proxy.

This setting cannot be changed through the web interface. You may change it by setting a value in your config.php file for the following config variable:

`$cfg->plugin_search_elasticsearch_indexingusername`.
