At the moment on my application i have a login page but if i send of one of my pages to someone who isnt a user it does not ask them to login therefore they can view the pages and access the system... how do i make my application more secure  
Hi Sat,

If you untick the Anonymous Role from your Screens, the Users that access those specific Screens will need to have a valid Login.
