We need this run time generated password so that survey does not work for forwarded links

There is a setting for tokens to limit them to a single use.

There is a setting for tokens to limit them to a single use.

But if I am right, we are now looking a solution where a participant can not give his/her token to other people. For that I guess it is theoretically impossible. But maybe another web page protected by shibboleth or similar could create a link with variable, and that would be used with the panel integration -feature?

I really appreciate your response buddies but its really difficult for me to understand anything

Let me lay down what i am looking for
1. We have closed survey
2. I want users to supply the OTP when they hit the survey LINK
3. We need this run time generated password so that survey does not work for forwarded links
4. OTP for participants - right now we are using access code but its a static value
 

OK : think i got it
Something like this : gitlab.com/SondagesPro/SurveyAccess/extraRegisterPassword Token + Password but with a OTP

Sample :
1. User receive the token link and click on it
2. System send an email (for example) with a one time password
3. System show to user a form and «enter your one time passord»
4. System check in one time password sent are the same then one time password sent by email.

The one time passowrd have a limited lifetiùme (one hour or less), user can click on a link to receive another one.

Can be done in plugin.
 

Can something like this be done with two surveys? First would be register-survey having a question of type equation using rand() and name 'foo', and it's end page would be 'http...realsurvey...&code={foo}'. Then after survey is done we could check if all answers are made in given time limit and each code used only once? Or the link can be sent as email too, using "basic admin notification" with {}-expression.
