Give Website Access To Some People Only By IP Address??

@yisrael-wix Is there any way of blocking people through code??
Or can we do this-

This is an idea from Russian-Dima old post .

If → YES, then my next question would be…
Am I not able to check the logged -in-state of each user?
If a user is already logged-in and another tries to log-in with the same login-data, but from another IP, am I not able to interrupt this, without the IP or MAC-verification?

Don’t I need just to look onto the log-in-state of this user-id, to find out if the user is already ONLINE?

If so, couldn’t I write some code which can prevent the second log-in?

These are just theoretical thoughts :grin:
