The root password must be at least six characters long; the password you type is not echoed to
the screen. You must enter the password twice; if the two passwords do not match, the installation
program asks you to enter them again.
You should make the root password something you can remember, but not something that is easy
for someone else to guess. Your name, your phone number,
qwerty
,
password, root
,
123456
, and
anteater
are all examples of bad passwords. Good passwords mix numerals with upper and lower
case letters and do not contain dictionary words:
Aard387vark
or
420BMttNT
, for example. Remember
that the password is case-sensitive. If you write down your password, keep it in a secure place.
However, it is recommended that you do not write down this or any password you create.
Note
Do not use one of the example passwords offered in this manual. Using one of these
passwords could be considered a security risk.
Note
To change your root password after you have completed the installation, use the
Root
Password Tool
.
Type the
system-config-rootpassword
command in a shell prompt to launch the
Root Password Tool
. If you are not root, it prompts you for the root password to continue.
