I would like to request additional features for ClickUp Forms, especially since most forms are shared via public links for external registrations and events:

The ability to limit form submissions to one per person (for example, by email address or unique identifier).

The option to password-protect forms or require an access code for submission.

Enhanced anti-duplicate measures, such as automatic flagging or blocking of repeat submissions based on a chosen field.

These features are essential for securely managing external registrations, event sign-ups, and other scenarios where submission control is important. Public forms are especially vulnerable to duplicate or unauthorized submissions, so these controls would greatly improve the utility and security of ClickUp Forms.
