I am trying to make a Log-in screen that load immediately after the user Logs in the Operating System (Windows Log-in, etc) and before he could initiate any process.
I want the screen to be locked, basically avoiding the user to manipulate with the authentication process and preventing the user to implement controls like crl+alt+del (or esc) else alt+tab.
It is actually a client server authentication where my server has the user database and it is must that the user cannot skip the Log-in.
Since its about tracking all the events of the user I wish to get the username and the password at the start-up to start the Log maintenance. If the user can some how skip the authentication, them my system fails.
It can’t be done — you essentially cannot circumvent Ctrl+Alt+Del. A far better option is to leverage the user’s original Login.
