RE: Required SecurityQuestion question

We have successfully import user accounts into Okta, though the first time a user authenticates via SSO they are prompted to create a security question/answer combination. What mandates this prompt, and how can this prompt be modified and disabled? Please advise, and thank you.

If you pre-populate the secret question and answer via API then it will not be shown to end user:
