Delete security questions from your account
It's possible to remove security questions as recovery info on your account by deleting them from your Account Information page. It's more secure to add an email address or phone number to verify and secure your account. If you've recently updated a mobile number or alternate email address, your security questions may have already been removed during the process.
Can't create new or edit exisiting questions - Your only option is to disable your current security questions. Once you've done this, you will not be able to view or create new questions.
- Go to your Yahoo Account Settings.
- Click Account security.
- Click Disable security questions.
- You'll be brought to a new page with your security questions.
- Click "Yes, secure my account."
- Click Continue.
