I think that this would be a great little feature addition that could be nested under ‘Tools’ in the web UI.
Functionality:
Audit your logins and provide a list of those which do not currently have 2FA configured (as assumed by the presence or lack of a TOTP credential for that login).
Purpose
Enable users to quickly identify logins for which they have not enabled 2FA . They could periodically check back to see if the provider has added it to their security offering.
