Description

In most parts of the documentation curl commands like this are suggested:

curl -X POST "https://<WAZUH_INDEXER_IP_ADDRESS>:9200/_flush" -u <USERNAME>:<PASSWORD> -k

Passing a password on command line is usually a very bad idea for security reasons as the password will e.g. end up the bash history (.bash_history) or similar.

For this reason i would suggest to update all curl commands throughout the documentation to just use -u <USERNAME> (without the :<PASSWORD>) and curl will then provide a prompt in the shell to insert the password afterwards like e.g.:

Enter host password for user 'admin':
