Secure screen blanking is a Timbuktu Pro security feature that prevents unauthorized access to your computer while it is being controlled by a remote user. When secure screen blanking is active, no one will be able to see what is happening on the computer's desktop. (They may be able to see the cursor move and hear any audio the computer generates.)
Secure screen blanking works differently in different situations: whether or not you are logged in to your computer, and—if you're logged in—whether or not your computer is locked before the remote user takes control.
You should always protect the security of your computer by using a password-protected screen saver. When you are away from your computer, the locking mechanism will help to ensure your security.
If you are working at your computer and a remote user controls it (for example, the Help Desk takes control to troubleshoot a problem you're having), the screen will not blank. You will be able to watch the remote user's actions and, if necessary, disconnect the user from your computer.
Note: Your screen will blank, even if you are using your computer, if you selected the Allow Controlling Users to Request Screen Blanking option in the Preferences dialog box and the remote user requests the screen to blank.
If your computer is locked and a remote user controls it, the screen will blank. You will not be able to activate your monitor until the remote user disconnects. When the remote user ends the control session, the Workstation Locked dialog box will reappear.
If you have not logged in to your computer and a remote user controls it, the screen will blank. You will not be able to activate your monitor until the remote user disconnects. When the remote user ends the control session, the Logon Information dialog box will reappear.
