I need to create a form that will allow users to login & have access to all of their submission

Is this possible?

If you want to create a form, please use this guide to help you get started: https://www.jotform.com/help/2-How-to-Create-Your-First-Web-Form

If you want your users to see their submission, you can add an autoresponder email. This will email the submitter a copy of the submission. Here's how: https://www.jotform.com/help/26-Setting-up-an-Autoresponder-Email

I hope that helps. If you have questions, please contact us again.

Thank you. Is there a way to allow the user to have login credentials to
login and see a list of all submissions?

1) This is possible to share a password protected form submissions page.

How to Share Form's Submissions Page

The submissions page will list all the submission entries related to that particular form. In other words, this may work for you if you have a separate form for each user.

We do not have a feature to provide each form user with login credentials to view their submitted entries.

2) There is an option to provide users with submission edit links. It will be one edit link per form entry.
