The end goal is to have a VPN solution that would allow Windows, Mac, and iOS users to connect securely, with a minimum of fuss. Tall order I know. :) I was looking at IKEv2 as it seemed to be supported natively on at least Windows and iOS, but windows clients insisted on using EAP-MSChapv2
Windows 10 should do TTLS.

No, IOS supports EAP-TLS, EAP-PEAP, EAP-TTLS.

IKEv2 based solutions are your best bet.

Anything that'll give you the plaintext password from the OTP server back will work with MSCHAPv2.
