You need to setup security for each user. You can setup security to disable different parts of your app to keep them out. You can make a runtime also but runtimes are single user only (non-networkable) and some other feature are disabled.
Here is a link to the filemaker security guide.
Thank you for your help, it will be for a single user account. Where can I find on how to make a runtime?
You will still want to setup security for runtime users.
There a few links about creating runtimes
Take a look and File Options in the File Menu.
You can set the file to automatically enter a limited access password that permits the users to use the database without having access to features/functions/layouts for which you don't want them to have access.
