Greetings to all once again!
I would like to know the answer to 2 questions.
Is it possible to install the panel on a subdomain, i.e. on dev.sayt.ru - I plan to do this so that the panel opens only at this address.
How to make access to the control panel admin panel (in other words, to the panel itself) only from a specific domain, that is, so that everything opens with just one link. (I want to protect myself from intruders, hide the panel). - Perhaps you can tell me the most correct way to do this, the point is to hide the control panel from prying eyes.
