Is there anyway that I can have a form BEHIND a log on screen ? i.e. not directly visible until approved user logs in?\

I understand that you are looking for ways to implement a login feature before allowing access to the form. You can achieve this in two different ways:
1. Password Protection Feature: FormNX does not have an in-built feature to show a login page and then display the form upon user approval. However, you can utilize the "Password Protection" feature. By enabling this feature, users will be required to enter a password to access the form. Once the correct password is entered, the form will be accessible. Refer to this documentation: https://formnx.com/details/docs/features/passwo... to know how to enable the "Password Protection" feature for your forms.

2. Embedding Forms in a Website with a Login Page: Another approach is to embed your forms within a website that already has a login page. After users log in to the website, they will be able to see and fill out the form seamlessly.
