Use case - trying to track how vendors are utilizing MFA (if they are).
For example:
MFA Forced - SAML/OIDC
MFA - Opt In
MFA - None
Another tag would be "Shared Accounts". For example, the one-off service that can't do multiple logins and an accounting team is sharing a login.
Ideally these tags would be added to the exporting of data reports.
