Administrator password
Setting an administrator password deters unauthorized persons from changing
configuration settings. If you are responsible for maintaining the settings of several
computers, you might want to set an administrator password.
After you set an administrator password, a password prompt is displayed each
time you try to access the IBM Setup Utility program. If you type the wrong
password, you will see an error message. If you type the wrong password three
times, you must turn the computer off and start again.
If both the user and administrator passwords are set, you can type either
password. However, to change any configuration settings, you must use your
administrator password.
Setting, changing, and deleting a password
To set, change, or delete a password, do the following:
Note: A password can be any combination of up to seven characters (A- Z, a-z,
and 0-9).
1. Start the IBM Setup Utility program (see “Starting the IBM Setup Utility
program” on page 55).
2. From the IBM Setup Utility program menu, select Security. Read the
information displayed at the right side of the screen.
