MFA: Using Authenticator App without Cell Service


You may find yourself in a situation where you have a weak or no signal to your cell phone or cannot receive notifications.  For those situations, you can use Microsoft Authenticator App’s One-time password code feature.

NOTE:  These instructions only apply if you have already installed the Microsoft Authenticator app and added it as a security method for your M365 Account.  See MFA: Setting up Multi-Factor Authentication (MFA) for M365 for instructions to set up the Microsoft Authenticator app for MFA.



Task: Use the Microsoft Authenticator App One-time password code option for MFA 



Step 1 - Sign into the service you want to use that is protected by M365 MFA (e.g. email, Canvas, etc.)

Step 2 - If Microsoft Authenticator - notification is your default MFA method, click or tap on I can't use my Microsoft Authenticator app right now.  Otherwise, skip to Step 3.

Step 4 - On your mobile device, open the Microsoft Authenticator app.  Tap on the USNH Account line.

Step 5 - Find the One-time password code in the app.  Also note the count-down timer (marked in yellow) - the code resets every 30 seconds, so if the timer is nearing zero, wait for the next code in a few seconds.
