In theory, certainly...  in practice, you will likely have to set up
some custom pieces to handle the interactions in PAM to use the Google
authenticator (if that is a specific requirement rather than a general
illustration).  Alternately, you could use a different authenticator
that is either easier make cygwin-friendly (or already is).

I've been considering trying to setup 2fa for my cygwin sshd myself
for years, but it's been a low priority since currently I have to
already be inside the network anyway, and disallow passwords to begin
with in most circumstances.
