I have to admistered an anonymous form to a group of students that should use the same computer in two in different moments. I need to guarantee that one student answer one only.
Do you have a solution?
Thanks a lot,

Unfortunately, you will need to use an identifier if you would like your users to submit only once. This will not be possible without an identifier.
You could however:
- Delete the browser's cookies whenever a student is finished answering the form, that will allow the next one to submit the form again. However, your users can also do this and can still make multiple submissions if they new this limitation, unless you'll have restrictions in the browser settings. But this will also add another step in your process.
Another possible solution is to print out small papers with unique codes then randomly let them pick one (draw lots). The unique codes will act as their identifier but will still remain anonymous.
The unique code then will be used as the unique question to limit the submission. Here's a guide on how to implement that: https://www.jotform.com/help/223-How-to-set-Form-Limits-Based-on-a-Unique-Question. With that, a specific unique code can only be used once per submission. If a user attempts to use the unique code again, he/she will not be able to submit the form.
Now when you tally each submission, you just need to check that each unique code is present on them.
I hope that helps.
