Hi Michal
make the plugin that you could hide the admin panel of the type that's an example of how this works for opencart( http://www.opencart.com/index.php?route=extension/extension/info&extension_id=9281&filter_search=Admin%20Login%20Security%20Lockdown%20Suite )

@rsn
Do you mean something like:
- autologin for users that you define (by IP)
- disable login for other IPs

it works by ip and shortcuts
see demo

screen plugin admin
on the screenshot function ip, and there on the keyboard combination

@rsn
It is nice idea, will think about it

@rsn very good idea, and it was safety....
