When configuring MFA, an authenticator app or phone number must be configured as the primary means of authentication.
At minimum you should have two methods of MFA configured, although setting up additional methods can be beneficial.
At Royal Holloway, we recommend that you setup the Microsoft Authenticator app and add a phone number for use with MFA.
Microsoft Authenticator App: The Microsoft Authenticator app is the simplest method of verifying your identity and is recommended by the university. It can be installed on an Android or iOS device.
There’s two ways the app can be used for MFA.
The first, which uses number matching, is generally the fastest and most convenient. You will need to download the app to your preferred device and set up authentication. This is the method we recommend.
You can also use the app to provide six-digit one-time passcodes, or OTP codes. OTP codes work well when you don’t have internet access on your phone or mobile device and you can’t receive notifications. Instead of approving a push notification, you type the OTP code into the browser you’re trying to sign in to. OTP codes refresh every 30 seconds, so they can be difficult to use before they time out, particularly if you have accessibility requirements.
SMS or Phone Call: If you don’t want to download an app, you can opt to register a phone number which you can use for authentication either by call or text message.
