Azure is a method of MFA to identify who you are, and most of the users use it for advance security. By using MFA for Office 365 account, we get a second access to logging in to verify that the person logged in is a person authorized or not. For this, he either confirms to a one time password, phone call or message. Only after satisfying its verification, that office can sign in 365 accounts.
