# Logging In

The next step to using your Red Hat Linux system is to log in. When you log in, you are introducing yourself to the system (also called authentication). If you type the wrong user name or password, you will not be allowed access to your system.

Unlike some other operating systems, your Red Hat Linux system uses accounts to manage privileges, maintain security, and more. Not all accounts are created equal: some accounts have fewer rights to access files or services than others.

| Note
| Like UNIX, Linux is case sensitive. That means that typing `root` refers to a different account than `Root`. By default, `root` refers to the root user (also known as the superuser), or system administrator.

If you have already created and logged into a user account, you can skip ahead to Chapter 2. If you created only the root account, read on to learn how to set up a user account.

If you did not create a user account during installation, you must log in as root. After you create a user account, it is highly recommended that you log in as that user instead of root to prevent accidental deletion of files or damage to your Red Hat Linux installation.

| Caution
| Because your Red Hat Linux system creates the root account during installation, some new users are tempted to use only this account for all of their activities. This is a dangerous idea, because the root account is allowed to do anything on the system. You can easily damage your system by accidentally deleting or modifying sensitive system files. You may be tempted to forego creating and using a user account during or after installation, but it is not recommended.

## Graphical Login

During installation, if you selected graphical as the login type, you will see a graphical login screen as shown in Figure 1-6. Again, unless you have chosen to give your machine its own hostname, which is primarily used in a network setting, your machine will probably be called `localhost`.

Figure 1-6. The Graphical Login Screen

To log in as root from the graphical login screen, type `root` at the login prompt, press [Enter], type the root password that you chose during installation at the password prompt, and press [Enter]. To log in as a regular user, type your username at the login prompt, type your password that you selected when creating the user at the password prompt, and press [Enter].

Logging in from the graphical login screen automatically starts the graphical desktop for you.

## Virtual Console Login

During installation, if you selected text as the login type, you will see a login prompt similar to the following after booting your system:

    Red Hat Linux release 8.0
    Kernel 2.4.18-14 on an i686

    localhost login:

Unless you have chosen to give your machine its own hostname, which is primarily used in a network setting, your machine will probably be called `localhost.localdomain`.

To log in as root from the console, type `root` at the login prompt, press [Enter], type the root password that you chose during installation at the password prompt, and press [Enter]. To log in as a regular user, type your username at the login prompt, press [Enter], type your password that you selected when creating the user at the password prompt, and press [Enter].

After logging in, you can type the command `startx` to start the graphical desktop.
