MFA for Remote Access

MultiFactor Authentication iconAll employees are required to use MFA when remotely accessing the College’s network resources.

The MFA for web-based remote access (remote.dtcc.edu) application can use a few authenticator apps. It will display a QR code which can be registered in your app of choice. I would recommend MS Authenticator since it can already receive push notifications for logging into Outlook and Office 365 sites. Google Authenticator, Authy and other apps which can scan QR codes can be used. After the initial enrollment, you will see a field to submit the six-digit code from the app when logging in with your username and password.

Microsoft Authenticator Phone-in Number approval

If you are using the Microsoft authenticator push notification for your multi factor authentication method you will be presented with a number on your screen to match the number on your phone.  This was done to increase the security of the multifactor authentication.  There have been several instances of MFA fatigue attacks, where bad actors are sending out multiple requests for access and these requests being accidently approved. By implementing number matching, users are prevented from accidentally approving MFA requests. The number will appear on the computer screen, and you will be required to enter the number into the authenticator app.  For more information, please check out Microsoft’s website link below:

Why do I have to use the Microsoft Authenticator App for Remote Access?

The Microsoft Authenticator app is required because the ability to put in a username and password is only available during login. During the login process, our authentication server creates a push notification that goes to the Authenticator app. There is no place to accept codes from alternative apps or text messages. The Microsoft Authenticator app is required because we are using Microsoft Azure to provide the MFA services.
