Every online surveys survey is given a unique URL when it is created. This is known as the public URL
The public URL can be found on your survey’s Distribute page.
The final part of the URL – known as the survey shortname – is based on the survey name in the first instance. This can be changed in the survey’s 
Distribution settings.
While your survey is in draft form, the public URL is not active. Anyone who visits the public URL while your survey is still in draft form will see a message stating that the survey cannot be found.
Once your survey has been launched, respondents can access it at the public URL.
If you have set up a survey password, respondents who visit the public URL will be asked to enter a password.
If you have set up a list of respondents, respondents who visit the public URL will be asked to enter a username and password. For surveys with a list of respondents, you can either provide your respondents with the public URL and a username and password, or you can provide them with a personalised URL which will allow them to access the survey without having to enter a username and password.
