Is there a way to preface access to filling out my form with a login system?

Is there a way to preface access to filling out my form with a login system?

Something that I can expose to the user that doesn't require them having a Jotforms account

We do not have a login system in forms, but we offer a workaround such as the below guide:

Or, just have a Short Text Entry field, add a conditional logic that if this new field is equal to the defined value, it will show the whole form fields.

Here's a demo you can check: https://form.jotform.com/91688039539977. Enter 123.
