  • RDAuth works by checking an email login against a whitelist and pass code combination. If the user passes this first check then an email will be sent to the user with a Verification Code - this confirms the user has control of the email account.

    Once this has been done a firewall rule is dynamically added for that users IP Address - which in turn allows the user to Remote Desktop onto the host machine (Or allow any other specified Port exception through the Windows Firewall eg. opening SQL or ERP ports).
