  <title>Change who has administrative privileges</title>

  <p>Administrative privileges are a way of deciding who can make changes to
  important parts of the system. You can change which users have administrative
  privileges and which ones do not. They are a good way of keeping your system
  secure and preventing potentially damaging unauthorized changes.</p>

  <p>You need <link xref="user-admin-explain">administrator privileges</link>
  to change account types.</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Users</gui>.</p>
    </item>
    <item>
      <p>Click <gui>Users</gui> to open the panel.</p>
    </item>
    <item>
      <p>Press <gui style="button">Unlock</gui> in the top right corner and
      type in your password when prompted.</p>
    </item>
    <item>
      <p>Select the user whose privileges you want to change.</p>
    </item>
    <item>
      <p>Click the label <gui>Standard</gui> next to <gui>Account Type</gui>
      and select <gui>Administrator</gui>.</p>
    </item>
    <item>
      <p>The user's privileges will be changed when they next log in.</p>
    </item>
  </steps>

  <note>
    <p>The first user account on the system is usually the one that has
    administrator privileges. This is the user account that was created when
    you first installed the system.</p>
    <p>It is unwise to have too many users with <gui>Administrator</gui>
    privileges on one system.</p>
