The installer creates your system administrator account.
It’s probably a good idea to create a second, regular user account for everyday use.
Why a Second Account?
BcalcOS disables the root user. The account created during installation serves as the system administrator, with full sudo privileges.
sudo stands for “superuser do.” It allows an authorized user to run commands with administrative privileges.
That account can install and remove software, change system-wide settings, and access or delete files belonging to other users.
For everyday tasks like browsing, email, documents, and media, those privileges are rarely needed.
A regular user account keeps administrative tasks deliberate. When you need to perform an administrative task, you can use sudo to request elevated privileges.
Creating a Regular User Account
There are two ways to do this.
Option 1: The Welcome Center
The BcalcOS Welcome Center can create a regular user account for you. Select the Create New User option and follow the prompts.
Option 2: The Terminal
Use the standard command:
sudo adduser username
Replace username with your chosen account name. You’ll be prompted to set a password and provide a few optional details.
The new account is a regular user account and is not a member of the sudo group.
Switching Accounts
Log out of your current session and log in with the new account.
Alternatively, you can switch to the new user’s shell temporarily from a terminal:
su - username
Replace username with the account name. Enter that user’s password when prompted.
TL;DR
Everyday tasks rarely need administrator privileges. Create a regular user account for daily use, and reserve the administrator account for tasks that require elevated privileges. The Welcome Center makes it easy.
