Logging in as a user and managing multi-user environments
Login is the process during which a user identifies themselves in the system, usually by providing a username and password, a couple of pieces of information often referred to as credentials.
The system can be accessed in many ways. The initial case for this, which we are covering here, is how a user accesses it when they install a physical machine (such as a laptop) or via the virtualization software interface. In this case, we are accessing the system through a console.
During installation, the user was created with an assigned password, and no graphical interface was installed. We will access the system in this case via its text console. The first thing we are going to do is to log in to the system using it. Once we start the machine and the boot process is completed, we will enter, by default, the multi-user text mode environment in which we are being requested to provide our login:
