Thanks kh99,
lets say I have here:
https://vborg.vbsupport.ru/profile.php?do=editprofile
a private profile user field with a user's home address or whatever sensitive data.
I would like to make this area more secure, as I said, when a user logs in on a public computer and forgets to log out, somebody else can easy access
https://vborg.vbsupport.ru/profile.php?do=editprofile and see the data which is supposed to be private.
In other words - i'd like to make the usercp area secure as modcp or admincp area which requires logging in after certain inactivity time ignoring the ticked "Remember me" option.
