Self-service MFA changes not possible for users
Spent a fairly long time investigating this ourselves and with MS support regarding what is clearly a bug regarding MFA, however fobbed off yesterday with a "By Design" response! In a nutshell - ...

This additional verification when performing certain actions, such as updating security details, is indeed by design. And it's the same with pretty much every other cloud service. User can ask their IT folks to reset their MFA status, and admins need to plan accordingly (a break-glass account).

That isn't correct though is it? It isn't the case for Gmail, it isn't the case for any of my financial accounts, online storage accounts or utilities. If MFA is not enabled on site, why is it suddenly enforced when changing a detail they would otherwise have access to if MFA was entirely disabled? The user has already been vetted securely via conditional access and local AD so surely there must be an option provided to bypass this? We "only" have 1300 users - is this also the case for larger establishments with tens of thousands and minimal IT teams?
- PolymathicMay 07, 2021Copper ContributorI sympathize, but I think you've framed this in a way that might not be the best comparison.
Changing an MFA credential/token is arguably an administrative act, even if the user is doing it. My experience with Google has been very similar in circumstances like the one you're describing. I don't think you can compare this with a circumstance where "MFA was entirely disabled" because even your own situation doesn't sound like that. That's before we even get to questions of whether it's advisable to run with no MFA at all. Architecture is best derived from your own threat model, but these days, it's difficult to make the case that a username/password tuple is a robust credential for anything important. Part of why you'll find pretty much any competent cloud service provider requiring a little additional assurance for credential administration is that credential theft is by far the primary risk to cloud service users (and operators). MS has written volumes about that, but they're not unique.
