Hello,

not a scheduled task. This should be handled per request or per page load.

If you want to do this per request, you can take advantage of global events -> in your case RequestEvents.Begin.Execute:

https://docs.kentico.com/display/K9/Reference+-+Global+system+events

If you want to do it per page load, then you can customize/clone the PortalTemplate and do the check there or you can create a new web part and place it on your master page.

And the the IP address for checking in scenarios above would be stored directly to the user (CMS_User table) or in some custom table/custom class with a linkage to a user (recommended).

Best regards,
Jan Hermann

Hello,

you can for instance log the IP addresses during the authentication and then add a check if the IP of a request matches last logged IP address and logout the user if it does not.

Hi Jan Hermann,

I have already tired it, I'm writing it in a Scheduler task Unable to get the User status whether the User is Authenticated or not. And the User Details like User Name,IP Address of the User. HttpContext is getting Null.

Thanks & Regards Rajiv
