2 factor authentication

we have a mixed mcrosoft environment of windows v7 and windows 10 (pro 64 bit) clients attached to a couple of hyperv 2012r2 servers and one separate exchange 2010 server in a stand alone 2012r2 server.

we currently implement a single stage complex password authentication.

however we have been asked to provide 2 factor authentication for our administrator and our finance group (to start with) with a view to pushing this out to all in months to come.

can anyone advise on the best (simplest cost effective) way to achieve this.

any advice much appreciated.

many thanks

i will look at the recommended products thanks. does microsoft windows / server not offer anything within the existing os?

I suppose you could get into things like AD Federation Services. Here's an article from a contributor talking about how they did it: https://docs.microsoft.com/en-us/windows-server/identity/ad-fs/operations/manage-risk-with-additional-multi-factor-authentication-for-sensitive-applications

But overall, there are many approaches.
