Starting with Windows 10 build 17063, Microsoft added the use of security questions to local accounts in Windows 10.
Security questions will provide an extra layer of protection for your local account in case you forget your password.
If you already have a local account, you can add security questions. 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. Once your security questions are set up, if you find yourself unable to remember your password on the sign-in screen, you will see a link to reset your password, whereupon clicking youâ€™ll be prompted to enter the answers to your security questions.
Starting with Windows 10 build 18237, a new group policy was added for preventing the use of security questions for local accounts. If you enable this policy setting, local users wonâ€™t be able to set up and use security questions to reset their passwords at sign in.
This tutorial will show you how to enable or disable the use of security questions for local accounts to reset passwords in Windows 10.
