By default, buttons do not have any pre-set security meaning that all users will have access to the button when it is published by an administrator.
Each button configured in Scan2x can optionally be assigned a set of permissions, governing whether the button is displayed for particular users or not.
Permission to view a button is set by adding users and/or user groups to the lists in the screenshot below.
The Groups tab allows for the viewing of existing groups set (the list below is empty) and for the adding and editing of groups if the Show All Groups checkbox is ticked.
The User tab works the same way and is used when you wish to add an individual user to a button.
