How to use Security
Security is one of the menus found under the Settings-tab.
You can choose to have the quest be password protected by selecting the Require Password from Respondents option. The default password in the box below is randomly generated, but you can change it to something else by simply writing the wanted password in the box. Remember to Save after any changes.
You can also select what type of distribution that will trigger the password requirement. Default are only Distribute by link selected, but if you want the additional security layer you can be flexible and include both Email and SMS.
