Currently running ADFS 2016 with Duo as our MFA provider. We are planning to move to O365 MFA, and would like to do it in a phased migration. A quick test shows that if both providers are selected in the configuration, the user is prompted to select which provider to use. Two questions, 1) is there a way to customize this selection screen? and 2) is there a way to define which provider a user is taken to based on group membership in AD? Thanks.
