Hi @Tybe_sacha
So you're through the completion of the auto security setup! Excellent.
What you don't get with that is HTTPS between your browser and Kibana
No, you don't need to follow all the steps from the beginning. Everything is done except for HTTPS on Kibana 5601
Encrypt traffic between your browser and Kibana are the steps for that.
Of course if you do a self-signed cert which is okay ...your browser is going to complain... But that's okay, you're just going to need to accept it or this is where a publicly signed certificate would work better.
That's your choice.
