Is it possible to authenticate ISE TACACS using Google Authenticator

CCC3
Level 1
Level 1

ISE is using 3.2 Patch 5.

I'm doing TACACS authentication through ISE
I want to do 2FA authentication using OTP.

DUO confirmed that it is possible, but I understand that it costs extra.

So I'm looking into whether there's any other way.

Among them, I wonder if Google Authenticator can support that feature.

And if there is any other way, please let me know.

What mechanism does Google Authenticator have to integrate with ISE?  Does it support RADIUS Proxy?  It certainly has no native local integration like DUO.
