We're currently using WordFence to securely log member users in by cell phone for a secure Document Management & Sharing solution. (P.S. I am hoping for an update to allow a separate field entry for the cell code, rather than force users to re-enter their password - but I digress...)
So it makes sense that once these users walks away from their computer, or in a public or kiosk situation, we want to ensure that the security of their account and the documents are protected by a settable idle timeout, with an admin selectable landing page for the logout. (i.e. "You have been logged out due to inactivity.")
In my case I need a selectable landing page for logoff because we want to hide the login page (it's already obscured by Theme My Login).
It made some sense to me that this is an extension for security of a WordPress site that might fall under the WordFence scope.
Thank you for considering it!
