3.2.1 Password Security
This computer supports two security password features—a setup password and a power-on
password. The power-on password prevents unauthorized use of the computer by requiring entry
of a password to access applications or data each time the computer is turned on or restarted. The
setup password specifically prevents unauthorized access to Computer Setup, and can also be
used as an override to the power-on password. That is, when prompted for the power-on
password, entering the setup password instead will allow access to the computer.
A network-wide setup password can be established to enable the system administrator to log in to
all network systems to perform maintenance without having to know the power-on password,
even if one has been established.
Establishing a Setup Password Using Computer Setup
Establishing a setup-on password through Computer Setup prevents reconfiguration of the
computer (use of the Computer Setup utility) until the password is entered.
