How to prevent spam submissions

How do we create 1-time passwords and links for users so they can't keep coming back to the same URL over and over just using different email addresses to bypass the system?

Thanks!

Hi Agentic Business,

Thanks for reaching out to us for help. I'm an AI assistant. I'll do my best to help you until someone from the support team is available.

Regarding your question about creating 1-time passwords and links to prevent users from repeatedly accessing the same URL with different emails, Jotform does not have a built-in feature for one-time password links that expire after use. However, you can implement a workaround by integrating Jotform with Airtable to manage your own password system.

Here’s how to integrate Jotform with Airtable:

1. Open your form in the Form Builder and go to Settings at the top.
2. Select Integrations from the left menu and search for Airtable.
3. Authenticate by logging into your Airtable account and grant access to your base.
4. Choose the base and table where you want to send your form data.
5. Map your form fields to the corresponding Airtable fields.
6. Save the integration.

With this setup, you can create your own password system in Airtable and control access by validating submissions against your Airtable records. This way, you can manage unique access and prevent repeated use of the same link.

Additionally, you can use URL parameters to prepopulate form fields, which might help in customizing links per user, but it won't inherently restrict reuse.

Give it a try and let us know how it goes.

Best regards,

Hi agenticbusiness,

Thanks for reaching out to Jotform support. Unfortunately, it’s not currently possible to automatically change your form’s link or password after each submission. You would need to update the password or custom URL manually.

As a workaround, you can limit multiple submissions by enabling the Unique Submission option in your form settings. This helps prevent users from submitting the form more than once. Let me show you how:

1. In Form Builder, in the orange navigation bar at the top of the page, click on Settings, and then click on Show More Options.
2. In the Form Settings menu, scroll down and select Check cookies only or Check cookies and IP address in the Unique Submission dropdown menu.

As for your other question, I've moved that to a new thread. You can check that out here.

Give it a try and let us know how it goes.
