By default, the tool only allows you to change certain settings regarding your account. This is because only the root user is allowed to configure users and groups. To unlock the configuration tool for all kinds of changes, click the Unlock button in the top-right corner of the window, and provide the correct password when prompted.
4.2.1. Configuring an Account
To change the image associated with an account, click the icon next to the account name and either select a picture from the pulldown list, or click to use an image from your local drive.
To change the name associated with an account, click the name next to the icon to edit it.
To change the account type, click the text next to the label. Note that this change requires the configuration tool to be unlocked even if you are changing your own account.
To change the default language for an account, click the text next to the Language label and select a language from the list.
To change the password, click the field next to the Password label. A dialog box appears, allowing you to set the new password. Note that the current password must be provided in order to confirm the change. Once done, click the Change button to save the change.
It is advisable to use a much longer password, as this makes it more difficult for an intruder to guess it and access the account without permission. It is also recommended that the password not be based on a dictionary term: use a combination of letters, numbers and special characters.
Finally, to set up automatic login for a particular account, enable the Automatic Login switch. The configuration tool must be unlocked to make this change.
