5.2   System Logon

 

5.2.1     Meaning of Logon

 

"Logon" means that a "worker" is assigned to perform work on a computer system, obtain work privilege, and enter the computer system. In a computer system, the worker is usually represented as a "user account", and an ID is assigned to the account different from other user accounts, and each ID is also usually designated with a password. Therefore, in the logon process, the user account ID and the password for the account are input to check whether the corresponding ID is already registered or the password is matched with the one registered with the corresponding ID.

 


 

5.2.2     Default User Account "pi"

 

Raspberry Pi has a built-in user accounts for installing and managing the system when the system is installed, one of which is "pi" account with the pre-assigned password "raspberry". Therefore, you can use this default user account immediately without any extra work.

 


 

5.2.3     Logon Processing

 

When the booting process is completed, the system logon screen appears. After entering the user ID and pressing the [Enter] key, you will be prompted to enter the password, then enter the correct password for the user and press the [Enter] key to complete the Logon procedure.

 

When the normal logon is completed with the default user account "pi", a prompt like "pi @ raspberrypi ~ $" appears at the bottom of the screen as shown below. This prompt means here you can enter commands to run the computer. It is then that the sysem is ready for users to enter the desired command on the computer.
