If you’re considering Office 365 or have started with the free trial then you’d be well placed to head over and check out the Office 365 Service Descriptions where you’ll find some really deep information about what’s included in each part of the service. I’ve seen some mention of Office 365 not providing two factor authentication (some competitors doo)…well actually Office 365 does too as it says in the Identity Service Description:
Two-factor authentication (also called strong authentication) provides improved security by requiring users to meet two authentication criteria such as a user name/password combination and a token or certificate.
To use two-factor authentication, you must implement an single sign-on strategy using Active Directory Federation Services 2.0 with Office 365. When planning your implementation, consider whether users have a supported operating system, are inside or outside the corporate network, and are using rich clients or web browsers. Also consider the ability of your authentication provider to interoperate with other services.
These guides are essential for anyone working their way through deployment of Office 365 in a large environment and probably for anyone considering the move
