Does JotForm have an option for respondents to log in prior?

when i was using other form maker that having same method with jotform came with edit link to update data later time, i found some data was gone missing, it was because some sort of cache timeout. this is the reason i am looking for online form that has login username and password.

Hello Ian - We do not have any option for respondents to log in to edit their submissions. But, edit links can not be expired for our users. Form respondents can edit their submissions as long as submissions are present in the account, which owns the form. 

Hope this information helps.
