Advanced 2FA methods for Sophos UTM?

Question

Hi there, 
 I'm surprised that I haven't found any other 2FA method for the Sophos UTM than the stone-age TOTP. This is very awkward, especially for users. 
 Other manufacturers show how modern 2FA can work. You log in by entering your UN and PW and simply confirm the login with an app that makes itself known specifically for this purpose. 
 Maybe I've missed something and there is such a function (perhaps with external service providers) with the UTM? 
 
 Thanks a lot

UTM only supports Radius externally, which can support more than OTP. But overall, UTM will go EOL soonish (2 years) and there is not the plan to implement native SAML integration.
