If you do not own a smartphone, or plan to be in a part of the world where you will not have Internet access and are therefore unable to use Microsoft Authenticator, a physical token may be utilized.
Microsoft MFA provides multiple options for authenticating your log in credentials, including the Microsoft Authenticator App, voice calls and text messages to your cell phone, voice calls to a landline office phone, and the use of physical hardware tokens (also called FOBs). It is recommended that users have at least two authentication options registered.
