Hello everyone, I am conducting a study where I am using tokens, so several links were generated for the client.

In addition to this, the client asks me to add a parameter to identify in the database the number of the participant who answers the question.
So far there is no problem since unique passwords were made for the participants and the "LSid" parameter was added to record the participant's code.

But the problem is that when they try to enter the league it sends them the message that the password does not match.

I leave three examples of what I am doing.

qar.com.mx/online/index.php/281255?token...Sid=6136598132896365
The version I use is 3.25.10

Thank you all
 

It's because user (you maybe) already start a survey with another token.

2 solution :
1. Reload page : because it's only for you : user receive one token code.
2. Add &newtest=Y in the url : previous session was deleted before checking token.
