• 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. Options include:
  - USE SYSTEM LOGON PASSWORD: The software will expect the user to type in their logon password - the 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.
  - Added support for alternate characters on international keyboards in the password.

• Grant access to other users. Ideal for multiple-user shared computer environments. Enables an adminstrator, 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).
  - New "unlock dialog" 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 program 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. This time-savings feature enables an administrator to makde configuration changes once, and have them applied to all users of that system.

Who Needs "Transparent Screen Lock" ?

Anyone who needs to Password Protect access to their workstation or server.

TSL provides a secure password mechanism for Win2k/XP/2003/Vista - and runs "transparently" - so you can still monitor the programs that are running. This is ideal for:

• System Administrators:control access to single-user or multi-user systems in a corporate environment.

• Labs and Production Floors: monitor processes while maintaining access control: 'see, but do not touch'.

• Retail Stores, Kiosks, Tradeshow Demos: prevent unauthorized access.

• Home users: parents can control a child's computer time; email or instant message users can monitor incoming messages, while restricting access to your computer.
