Introduction
Azure Multi-Factor Authentication (MFA) helps protect access to information and applications while keeping up simplicity for users. It provides extra security by requiring a second form of authentication/verification and conveys solid validation by means of a scope of simple to utilize confirmation techniques.
Azure Multi-Factor Authentication (MFA) Provider
There are two types of Auth providers, and the refinement is around how your Azure subscription is charged. The pre-authentication option calculates the number of authentications performed against your tenant in a month. This alternative is best if you have a few users authenticating only occasionally. The per-client option calculates the number of individuals in your tenant who perform two-step verification in a month. This choice is ideal on the off chance that you have a few clients with licenses yet need to stretch out MFA to more clients past your authorizing limits.
