What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
We can help you with changing the username, if you can provide us with the new username you want to change.
Please be noted that if any of your JotForms are embedded or shared using custom URL that uses username will not work after changing username. You'll need to re-embed or re-share the JotForm URL or with the changed username in order to receive your submissions.
Hope this information helps.
