Logging into a Linux system

Access to a system requires authentication. The most common method used to authenticate a user is a login process, by entering a valid user name and password. There are two types of login screens: Virtual consoles (text-based) and Graphical logins (called display managers)

Virtual Consol login:

localhost login: heart (user name)

Virtual login

Password: 123456        (password)
Last   login: Mon Sep 15 19:30:46 on :0
[heart@localhost   heart]$   

root=  User Name
localhost= Computer Name
heart=  Working Directory

Virtual consol login

$= Symbol Of User

Graphical logins:

User Name:        Heart

Password:           123456     

 

Login using login name and password. Each user has a home directory for personal file storage. By default graphical login for Red Hat Enterprise Linux is gdm, the GNOME Display Manger (display manager is the technical login).And again by default, the display manager will start the GNOMR desktop

Notice that your password is not displayed when typed in Virtual consol
