Does anyone have any experience with enabling 2factor authentication on a public facing OWA (exchange webmail)? I would like to enable this however i'm concerned as to how it would affect mobile devices from accessing mail.
Or put a different way: "which mobile Exchange clients support 2FA?" ?
Duo Security supports two-factor authentication for OWA. I'm not sure if you're also asking about the built-in clients for the various Activesync-capable devices...
Can you clarify?
