Is it required a log in to submit forms?

Hello, 

I am interested in using jotforms for our company.  Do users have to sign in or register for a log in to fill out and complete the forms?

No, it's not required to create an account or have log in information in order to fill out the forms, you will only need to share the forms with the users and they can submit them without any problem, now you, as the form owner, must log into your JotForm account in order to make changes to the form or view the submissions data. 

Now, please note that it's not allowed to ask for log in information, cc details nor personal data (personal data might be allowed only if it's required for your business and you provide a proof of that), your account may be suspended due to this, to get more information about what you cannot ask on your forms, please check our terms: https://www.jotform.com/help/8-Terms-of-Use 

If you have questions, please let us know.
