The surveys that can be answered only after adding code or password are considered as password-protected surveys. Adding a password to your surveys ensures that they are available to only those respondents whom you have emailed or invited. Configuring a unique password per respondent allows you to set up authentication for your survey. To view and answer the survey, respondents will be required to log in with their unique password. For more security, you can enable email address/password validation on the survey. Respondents will have to enter their email address along with the individual password to access the survey.
You can embed a link to your survey in the invitation email. Consider email/password type of authentication is set on the survey. When the respondent clicks on the link, it will prompt to enter the credentials. The respondent will be able to log in only by using the correct email address and password.
In times when data breaches are rampant, it becomes imperative to put the security of the survey data on top priority. Setting a unique password for each respondent will restrict unsolicited access and secure your surveys. It also helps when you embed an anonymous link in the email and want to restrict who can answer the survey. Configuring a password for each respondent will help you to gather responses only from your target audience.
Survey authentication allows you to control who can see and respond to your surveys. QuestionPro offers multiple types of authentication methods to choose from. You can select one of them depending on the level of security you need.
