I have freeradius working with Activedirectory to authenticate users on a Fortinet Gateway.

I'd like to add OTP so users can use Google Auth, Authy, Microsoft Authenticator or their favourite OTP software.

What are people currently using and is there a recommendation for something on the Freeradius server? I've searched for options and getting a million answers only to find after going down the garden path there are issues with how codes are issued. Just after some tips on what people have used.

You can use whatever OTP solution works for you. However, the server comes with a TOTP module that's compatible with Google Auth, Apple, and anything else that does standard TOTP. Alan DeKok.
