Starting with Windows 10 spring creator update you can add the security questions on lock screen in Windows 10 for local account.
If you are installing a new PC using a local account, setup will walk you through adding these questions and answers right there in the workflow.
If you are already using a local user account which doesn’t have security questions attached to it, you can add security questions to your account as well. Microsoft allows you to select any three security questions out of given six and answer them. Following are the questions in the current build.
1. What was your first pets name?
2. What’s the name of the city where you were born?
3. What was your childhood nickname?
4. What’s the name of the city where your parents met?
5. What’s the first name of your oldest cousin?
6. What’s the name of the first school you attended?
