For some reason, password/user doesn't work on my cluster, it used to work but now it doesn't. I don't know if it is because I had to reboot all servers (working with 3 servers). Now I would like to reset all password (kibana/elasticsearch/logstash/...). I configured password using this:
Probably, I have to run the same command again, but I'm not sure. And want to know if running the command will reset my data on Kibana/Elastic (dashboards/indices).
Also why password is not working? If I restart the server elastic/kibana might forget password?
