movement of employees and visitors, as well as in high security
environments such as financial institutions and banks, hospitals and
pharmaceutical research facilities, government offices and military

individuals in both stand-alone and multiple-user shared computer
environments, Transparent Screen Lock is ideal for facilities which
must ensure compliance to the 21 CFR Part 11 code of federal
regulations.

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.

- accept any valid username/password combination in the facility,
- accept members of a specified "User Group" (local or global).

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.

program and associated icons will automatically be available on the
