Password Protection
Any attempts to access your workstation or server while TSL is running (by typing a key or moving the mouse) require a valid username and password to be entered. If no password is entered, the password dialog box will disappear after 5 seconds, and the system will remain locked. 

Options include:

- USE WINDOWS LOGON PASSWORD: The software will expect the user to type in their Windows logon password (same password that is used to log on to their account) Note: This is the default option.
- CONFIGURE WITH NEW PASSWORD: You may also choose to enter a different password manually via the configuration program.
- ALTERNATE CHARACTERS: On international keyboards, alternate characters can be used in the password.

Grant access to specific users/groups
Ideal for multiple-user shared computer environments. Enables an administrator, a specified group of users, and/or other authenticated users to access the system without closing the current session. Options include:
- Accept current user's password only
- Accept users with Administrative Privileges
- Accept any valid username/password combination in the facility
- Accept members of a specified "User Group" (local or global)
- "Unlock" configuration tab provides additional control over how the password dialog box is displayed, including options to automatically populate the username field, restrict access to users of one domain only, and configure a timeout value.

Simplified configuration in a multiple-user shared computer environment
- An Administrator can install the program once, and the program and associated icons will automatically be available on the desktop of all users sharing the computer.
- Make program settings on a per-user basis or on a system/machine basis. 
- Manage TSL configuration using Group Policy Objects (GPOs)

Secure Remote Desktops
Allows users to view a remote desktop while preventing any interaction with the remote system.

Control Usage of CTRL-ALT-DEL 
Control the CTRL-ALT-DEL key sequence.  In selecting this option, no menu will be displayed if the user presses CTRL-ALT-DEL.

Option to shutdown system or Logoff current user after a specified number of invalid logon attempts
Provides additional system security.

Administrative Control
Choose to allow only a user with full Administrative Privileges to access the configuration program.

Log File
Create a log file to document activity and logon attempts.
- Document the time and date of when TSL was active/inactive
- Provide a list of invalid login attempts
- The log file may be saved either locally, at a remote network location
- For maximum security, save the log file to the Windows Application Event Log

Scheduling Options
Run TSL automatically at a preset time interval like a screensaver

OR

Run TSL immediately by clicking on the quick-launch icon in the Windows Tool Tray, or by using a Windows Hotkey. 

Blank Screen Option
Choose to display a blank screen when the system is locked, rather than viewing programs running on the desktop. Ideal for preventing unauthorized system access, in a stand-alone or multi-user environment with all the features listed here, while preventing the display of confidential information.

Dim Screen Option
Control the amount of opacity of the display when the system is locked.

Enter an integer between 0 (completely transparent) and 100 (black display)

User-friendly Setup Program
Includes various user-friendly features, including:
- Embedded context-sensitive help file
- Tip of the day upon startup
- Keyboard shortcuts for mouseless operation.
