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.
