Duo Alternatives?

[O'Dowd, Josh]

I am doing due diligence for a likely Duo purchase, which I have demo'd on campus using the outstanding Shibboleth native support.  I am curious if there are any known legitimate alternatives to Duo as a 2nd factor solution WITHOUT sacrificing Shibboleth IdP front-channel password authentication as the 1st factor.

We are not considering a custom built solution at this time.

I truly appreciate any feedback from the Shibboleth community.

Thank You!
