About this task
To login to the CLI, you need a username and a password. Initially, there is only one user, named root (with password root), on the system. It is recommended to change the root user password to prevent unauthorized entry into the system. The root user has Administrative privileges. You can add more users with the username command.
Note:
When you open the CLI interface, you are prompted for a username. Enter the username and press Enter. Enter your password at the password prompt, and press Enter. Once you have logged in, you can execute all the CLI commands that are permitted at your user level.
