This section provides instructions for setting up Multi-factor Authentication (MFA) for your M365 account on a new or different phone device.  This is for use when replacing a phone (or mobile device) that was already set up with both:

 

1. the Microsoft Authenticator app for use with MFA for M365 at IVCC
   1. See Setting up Multi-Factor Authentication (MFA) for M365 if you need to set up Microsoft Authenticator for MFA for the first time.
2. plus at least one backup method. 

2. See Adding Backup Multi-Factor Authentication (MFA) Methods to add a backup method. 

After you have two or more MFA methods and have your existing phone number ported to a new phone or device, then you are ready to follow these steps. 

 

Important: If you did NOT have a backup MFA method on your old phone, then you must call the Help Desk or visit in person to set up the Microsoft Authenticator app on your new phone.

 

First: Please install the app on your new phone or device before you begin the set up steps below.  You will find step-by-step instructions in the section Installing the Microsoft Authenticator App.
