I need to setup MFA for Office365. The issue I am running into is that we have a department where they are discouraged from having personal phones at their desk during the day, they use a shared extension so calls ring on everyone's phone and some of them move between a few different locations. Because of this I don't want to use SMS or call back options. It also means I can not install apps on a cell phone for authentication.
Has anyone setup on the local computers a software token system to connect to Office365?
