When using the "Forgot Password" or "Unlock Account" options under the Okta sign on the only two options that come up for MFA are email and text message. I have enabled both Google Authenticator and the Okta Verify App. Can you use those instead of email or text message? I haven't found any settigns that allows you to enable those options for the aforementioned links.
I also have Okta Verify App configured for my account, but can't use it for resetting my password or unlocking my account.
