Thank you for response, by MFA I mean the passcode verification method while users use "Forget Password Link"
Currently our password Self-Service policy has "Authenticator Mobile App" checked and set to Duo Mobile, but when users use "Forget Password" link they are only presented with Captcha and security Q&A set by them. Would like to have them enter passcode when they attempt to reset their forgotten password using "Forget Password" link.
