Introduction
The Multi-Factor Authenticator, also called Microsoft Authenticator, is a security tool for verifying your identity. The Microsoft Authenticator app is available for iPhone and Android devices. When you sign in to a new device or ISU application for the first time, you will be asked to open the Microsoft Authenticator app on your smartphone. The verification usually involves entering a two-digit code from the website into the app. If you change the phone number linked to the Microsoft Authenticator or reinstall the app, you may need to resync the method. This article explains how to regain access to your authentication method.
Reasons Why You Might Need to Reset
If you are no longer receiving notifications from the Microsoft Authenticator app, and cannot enter the two-digit verification code the following reasons could be why:
- You recently got a new phone and needed to reinstall the Microsoft Authenticator app
- Your phone number has changed
- You uninstalled and then reinstalled the Microsoft Authenticator app
- Your email was part of a security issue, so you had to reset your password and multi-factor authentication (MFA)
