When you are doing your initial setup, you may add as many devices as you like (landline and/or mobile). Subsequently, when you are logging in you can choose which device the authentication request is sent to and which authentication method you would like (via Duo Mobile App, SMS text message, or phone call).

How long does it take to enroll/register a device for MFA?

Typically, 5 minutes or less. ITS Help Desk can help with the setup process, if required

How many devices can I add?

There is no limit on the number of devices that can be added. We recommend that all users add
at least 2 devices, such as a cellphone/smartphone and a landline/desk phone.

Using MFA

How often do I need to use the second factor authentication?

You will be required to MFA every time you log in to the VPN service, when off-campus. When signing into OWA and my.fairfield.edu, you will have the option to remember your session for 24 hours. If you select this option, you will not be required to MFA on those services if you sign in again on the same device within 24 hours. This functionality is also browser based so if you switch browsers, the system will prompt you to MFA again even if you selected the option to remember your previous session.

Does it cost me money to authenticate with my phone?

“Push” authentication uses a very small amount of Internet data traffic to function (a few kilobytes per login). Text messages and voice calls are sent only when you request them, and would be billed by your carrier like any other text message or inbound voice call. The Duo mobile app also works like a token and will generate a passcode, this functionality will not require any data and works even when your smart phone is in “airplane” mode.

What if I forget my smartphone at home?

We encourage users to set up multiple authentication devices with MFA, so that when one method is unavailable, you have others from which to choose. For example, you could set up your smartphone for “push” and also your office phone and home phone to do callback. If none of your devices is available, contact the ITS Help Desk and they will be able to provide a one-time code after verifying your identity.

What happens if I lose my phone?

Contact the ITS Help Desk immediately if you lose your phone or suspect that it's been stolen.
The support specialist will disable it for MFA and help you log in using a one-time code. While it's important that you contact the Help Desk if you lose your phone, remember that your
password will still protect your account.
