Is the access token the same thing as an access code? I found the instructions below - is this correct? Also confirming that this means I have to create a code for each person, and this cannot be automatized.
Access Code (s)
A special case of marking is the access code (Access Codes). This is a one-time-password that allows him to access a questionnaire using the access restriction Access code.
For this to work, every participant needs his valid access code. They don't need to type it in by himself, instead add the access as the parameter s to the URL:
https://www.soscisurvey.de/demo/?s=AB123456
Access codes must only contain letters (A-Z) and digits (0-9).
Tip: When sending personalized URLs using access codes, participants are able to pause the interview and resume it later where they left off. This even works for questionnaires that are public. Nevertheless, every participant needs to have their own access code beforehand.
Important: An individual access code is only valid until the questionnaire was filled out and reached the last page. Afterwards, the access code won't work, any more. For more details see Access Codes.
