6.3.2. Setting Up Users And Passwords
Just before configuring the clock, the installer will allow you to set up the “root” account and/or an account for the first user. Other user accounts can be created after the installation has been completed.
6.3.2.1. Set the Root PasswordThe root account is also called the super-user; it is a login that bypasses all security protection on your system. The root account should only be used to perform system administration, and only used for as short a time as possible.
Any password you create should contain at least 6 characters, and should contain both upper- and lower-case characters, as well as punctuation characters. Take extra care when setting your root password, since it is such a powerful account. Avoid dictionary words or use of any personal information which could be guessed.
If anyone ever tells you they need your root password, be extremely wary. You should normally never give your root password out, unless you are administering a machine with more than one system administrator.
