Remote Desktop protection secured with ESET Secure Authentication (ESA) says ‘Incorrect password or username’

Issue

  • You are trying to log on to a computer via Remote Desktop Protocol (RDP) secured by ESA, but the logon fails with message “Incorrect password or username”, even though you are using proper login credentials
  • If ESA RDP protection is uninstalled, RDP logon works

Solution
