UserStrongAuthEnrollmentRequired - Due to a configuration change made by the admin such as a Conditional Access policy, per-user enforcement, or because the user moved to a new location, the user is required to use multifactor authentication. Either a managed user needs to register security info to complete multifactor authentication, or a federated user needs to get the multifactor claim from the federated identity provider.
