This second factor depends on the choices provided by the miniOrange and the option that the user feels is the best for him. This could be an OTP over Email, OTP over SMS, Microsoft Authenticator, or a Hardware Token. Once authenticated with the 2nd factor, the user gains access to his Microsoft 365 account.

Multifactor Authentication Methods

The Office 365 Multi-Factor Authentication (MFA) process is as follows:

  1. The user navigates to the Office 365 login page.
  2. Users enter a dedicated username and password for their Office 365 account. This is often called the primary factor of authentication. When a user submits the login credentials it’s checked whether the user exists within the database.
  3. If the login credentials match with the user, the second factor of authentication is shown to the user. E.g Pop up asking for OTP sent over SMS /Email
  4. When the user enters the second factor like OTP or Push notification, it’s checked against the database system if the second factor is correct.
  5. After successfully completing the second factor, the user is granted access to the Office 365 system.
  6. In the same manner, if you’ve got more MFA methods lined up, it’ll invite authentication for all of them and final permission is going to be granted.
