# Administrative tasks

For security reasons, administrative tasks in Xubuntu can only be performed by users with special administrative privileges. The first user account created during installation will, by default, be able to perform administrative tasks.

When you run an application that requires administrative privileges, you will be asked to enter your user password. This helps to protect your system from malicious files and lessens the chances that you will accidentally select options which may change the way your system works.

Each time you type your password, the system remembers it for 15 minutes so that you do not have to type it again.

Users must be a member of the 'sudo' group in order to carry out administrative operations. Information on how to change groups can be found below.

## Users and groups

When Xubuntu is installed, only one user account is created. If multiple users use the computer, it is highly encouraged to create separate user accounts for everybody. This allows users to have their individual settings, files and access rights.

To modify the users or groups on your system, navigate to &wm-users-groups;.

You need administrative rights to make changes to users and groups.
