/root
In Linux, the user account with full privileges is the root account. This account has unrestricted access to all commands and files on the system, allowing it to perform any administrative tasks, such as installing software, changing system configurations, and managing user permissions. It is important to use the root account cautiously, as improper use can lead to system instability or security vulnerabilities. Regular users can gain temporary root privileges using the sudo command if configured to do so.
do your own research
The first step when starting to use Linux is to understand that you need to create a new user account besides the root one you made during installation. The root account has access to all system files and other logins have limited access. This means that if something goes wrong such as a virus if you are logged in the root account then it can corrupt all files but as a normal user the damage is isolated.
Yes Linux does support the creation of multiple user accounts. If you wish to learn to use the command line, these commands are how you create a new account along with a password. 1) useradd "new account name" 2) passwd "name of new account" you will be prompted for a password then asked to retype it. to delete a user type: userdel "name of account" to delete the account and all the accounts files type: userdel -r "name of account" All of the commands I've listed must be run by the root account.
