You can easily secure your survey with a password for an added layer of security.
Click on Settings in the main menu of your survey editor.
Click Security in the left-hand menu, then turn on the activation slider next to Password protection and enter your desired password. Once activated, your survey is protected.
Don't forget to distribute the password to your respondents.
Tip: You can also restrict access to the survey to specific IP addresses. However, we recommend leaving this setting to your administrator. Please note that IP address restriction is not 100% secure.
