The User widget is the first widget. 
 
At a glance the User Widget provide you with 3 important numbers that are specific to the database you have selected.  The first number is the total number of users for the database. The Second number is the total number of active users for the database. Finally, the third number is the total active web users for the database. 
 
When you click the User Widget, you will be directed to the Manage User area.  This page is a list of users for the database. Users Management is covered in more detail later in this documentation.
