Adding a Backup Authentication Method for Microsoft MFA

Why add a second authentication method?

Entra MFA allows users to add multiple authentication methods including the Microsoft Authenticator mobile app and a phone number which allows for texted codes and calls.

Setting up two methods gives users more flexibility in how they sign in; the Authenticator App works over WiFi and cellular data, while the text/call work over cellular data and can be useful when no Wifi is available. The Authenticator app will work if the student travels internationally, as it works on any WiFi connection. When a student gets a new phone, if they keep the same phone number, rolling the Authenticator app over to the new device is a simpler process when they can use the call/text authentication method.

The instructions below will show you how to add a backup method, if you already have the Authenticator app, follow the steps to add auth by text. If you already have auth by text, follow the instructions to add the Authenticator app.
