How can this be set up? 

Admin user needs to configure "MFA settings" in the cidaas Admin Dashboard, where touchID/finger print, face recognition and several other authentication methods can be activated. 

Dashboard -> Multifactor Settings ->MFA Settings

These options are available for configuration also to the end-users under their respective profile settings, when they login to the business website/App.
