This is hopefully an easy question, and I apologize if the answer is obvious. I am a sociologist and not a programmer. I have a particularly long survey and pilot testers commented that while they took a break their browser reset, and they were not able to access their prior responses. I have been experimenting and reviewing prior forum posts that appear to be similar but did not locate a solution. I would like users to be given a random token that will appear in their url or in the survey, which they can use to access their prior responses. I don't want to allow public registration to a panel, as it is important to maintain anonymity.

I want to write at the top of the survey: If you would like more time, please click the save button at the top. You can resume the survey again by entering the current url for your survey: {URL.shown}.

The following forum posts seem to discuss similar concepts, but I did not yet succeed in implementing them:

forums.limesurvey.org/forum/design-issue...tion-using-chance-js

forums.limesurvey.org/forum/can-i-do-thi...-button-in-my-survey

Thank you so much in advance if you can provide assistance. I really appreciate this forum.

Why don't give advice to use Save at 1st page ?
Then : they can reload their survey at the last step.

The "Participant may save and resume later" function solves this problem!
Thank you.
