    Hello!

    Is it possible for a jotForm to recognize a device's unique ID and then display different information to the user based on that?


    For example, I'd like my form to always display to a user until they have completed it. Once they have completed it in its entirety - i'd love for the form to display a message that says 'Hello - you have already completed this form. Thank you!'

    Is this possible to do with Jotform?

    Hi Roey Kruvi,

    Good day to you! I understand that you wanted to prevent duplicate submissions, I too was looking for answers. While browsing through the forums, I chanced upon an answer that may be the best work around for this.

    The thread says that the best way to avoid form resubmission is to add a Captcha field on it and here's the link for the guide on doing so:

    Another option is to set a unique submissions, please see the link below:

    Lastly, you can also set form limits based on a unique question:
