When using the "Anonymous Survey Access" survey URL, your panelists cannot switch devices, and cannot continue the survey where they were left off after they close their browser without a new response generated. There is no information collected about them so Surveylet cannot email them their private survey link to continue edit their responses later on.
However, you can add a token into your survey that will allow them to see a private URL pointing to their own questionnaire which they can save and reuse for later access. The token is "<personal_survey_link>". It needs to be added into a Descriptive Label question's Question Details section. It does not work for any other question types.
How to use it?
In the "Click to write question details..." section switch on the HTML source so you can directly edit the code. You can do it by double-clicking in the "Click to write question details..." text; or hit the space bar and highlight the empty text.
You will see the air toolbar showing up. The first icon ("</>") is the HTML source code icon:
Add the <personal_survey_link> token with a description so panelists know what to do with it:
Click on the </> icon again to close the HTML source code editor. You will notice that the <personal_survey_link> token is not displayed, only your explanation:
The <personal_survey_link> token is only displayed to the panelist, and it displays the panelist's private encrypted URL to this questionnaire:
Panelist can only access his/her existing questionnaire through different devices or different browser sessions through the link that is displayed. S/he needs to save the link displayed so s/he can continue to edit the same questionnaire in a new session on the same or another device. Any new click on the original Anonymous Survey Access URL may result in the generation of a brand new response.
