After the linked bug has been fixed and talking with Victor about this from UX perspective, we should do the followings:

1. Modify the main config entries like this:
   • Multi-Factor Authentication
     • We keep this only this part of the title to show, that is the main config of the MFA.
   • IP Address Configuration
   • Time-Based One-Time Password Configuration
2. Create two sections on the main, Multi-Factor Authentication menu (see the multiple-section-headers.jpg attachment):
   • Multi-Factor Authentication (with the enable checkbox only)
   • Email One-Time Password Configuration (with all the other config entries on the page)

Acceptance Criteria

1. As an Instance Administrator, I want to have the Multi-Factor Authentication name of the first entry of the multi-factor authentication configuration entry list.
2. As an Instance Administrator, I want to have separate sections on the Multi-Factor Authentication main config entry page for the Enable checkbox with the name of Multi-Factor Authentication and for the Email OTP related config entries with Email One-Time Password Configuration.
