Watches might have access to sensitive data such as HTTP basic authentication information or details about your SMTP email service. You can encrypt this data by generating a key and adding some secure settings on each node in your cluster.

The system key is a symmetric key, so the same key must be used on every node in the cluster.

For example, run the following command to import the
system_keyfile on each node:
bin/elasticsearch-keystore add-file xpack.watcher.encryption_key <filepath>/system_key

Existing watches are not affected by these changes. Only watches that you create after following these steps have encryption enabled.
