Overview

DUO mobile is a form of multi-factor authentication that SIU uses to make your logins more secure. You can authenticate with DUO with a push notification, phone call, or a passcode. The DUO mobile application (which is required for push notifications) requires a phone with Android 8.0 or IOS 12.

It is recommended you install the DUO mobile app before you start the process of adding your device. You can find the app at your corresponding app store. Google Play for Android and App Store for Apple.

What is Multi-Factor Authentication?

Multi-Factor Authentication (MFA) is a two-step authentication process that increases security for your SIU credentials and accounts. MFA may seem unfamiliar, but MFA is an industry standard that is already used to protect financial, medical, and other important accounts. For example, more and more banks require credentials like a username and password to initiate the sign-in process, and then send a code via cell phone or email that must be entered to gain access to the account. OIT has put in the same protections at SIU.

Who is required to use DUO?

The following employees are required to use DUO authentication:

  • AP Staff
  • Faculty
  • Civil Service (including Extra-Help Appointments)
  • Volunteers
  • Restricted term appointments

Students with the following statuses are required to use DUO authentication:

  • Enrolled
  • Incomplete
  • Military Incomplete

In addition to the above, any accounts with VPN access or access to BigDawg(or any HPC) will require DUO authentication.

Currently, we do not require DUO authentication for students who are applicants or alumni (graduated). Retired employees are also currently exempt from requiring DUO as well.

Adding DUO devices

Adding a Device to DUO if there are no devices on account (First time users)

When you account is eligible for DUO and you attempt to login anywhere that requires DUO authentication (eg: netid.siu.edu or office.siu.edu) you will be prompted to set up your device with DUO.
In the example below, we will have examples a user would see if they are logging in at netid.siu.edu

To start please click on the green “Start Setup” button

DUO setup

Next you will select the type of device you are adding. Mobile phones and Tablets will need the DUO mobile application installed to take advantage of push notifications and passcodes. Mobile phone users who wish to not download the DUO app can only authenticate by phone call, test, or passcode.

Adding a Security/Hardware Token

Bypass Codes

DUO allows you to generate up to five bypass codes to use if you do not have access to your registered device.

First you will need to login at http://netid.siu.edu
When you get logged in, make sure that you are in the “My Profile” tab, and then click on the “Duo Security” tab beneath it. The screen should look like the one below once you click those tabs.

New Duo Security Tab in the NetID profile.

Once you are here, scroll down to the bottom of the page, and click on “Generate Random Codes“.

You will be given five codes. You can choose to print these codes by clicking the “Print Bypass Codes” button.
These codes can be used one time each and are valid for one year.

Using Passcodes

If you have a bypass code and would like to use it to log in, you can do so at the DUO login prompt by selecting “Enter a Passcode”.
Passcodes can also be found inside the DUO app. You may need to press the “show” link to the right to show your passcode within the app.

Once you’ve entered your passcode, please select Log In

Using DUO During International Travel

There are several options to take with DUO if you are traveling and will not have phone service to authenticate.

Smartphone/Tablet – Even with cellular service disabled or without a wifi connection, you may use the Duo Mobile app to generate a passcode that you can use to authentication. Simply choose the Enter a Passcode option when you get the Duo authentication prompt. To generate the passcode, open the Duo Mobile app on your phone and tap the down arrow symbol ? next to “SIU”.

Hardware token – if you don’t have a smartphone/tablet and you travel internationally often, you may want to get a hardware token (contact SalukiTech to start the process). Simply choose the Enter a Passcode option when you get the Duo authentication prompt and then enter the passcode that shows on the hardware token. Note: there is a $25 fee for hardware tokens as of August 1, 2020.

ByPass Code – If you won’t have a smartphone/tablet and a hardware token is not an option, it is possible to get a bypass code from netid.siu.edu in advance for 5 one time uses. This is good if you forget your device or for a short trip. Then, simply choose the Enter a Passcode option when you get the Duo authentication prompt and enter the bypass code that you were given.

Normal options – If you have a cellular service or a wifi connection, then you can simply use whatever authentication technique you normally use. The push, passcode, and phone options all work overseas. You can even add an international phone number as one of your authentication options.

You can also add a second device to your Duo Profile on netid.siu.edu for an international phone if you use a different device over-seas.

DUO timing out or error messages within DUO application

Occasionally users will receive an error that their request has timed out. This is usually caused by a networking issue or the devices clock is out of sync. Disconnecting and reconnecting from their network and updating their devices time is the first step to troubleshooting these issues.

If you encounter an error message such as the one above within the DUO app, please close the app, disconnect from your wireless network, reconnect, and open the app again.

If these troubleshooting methods do not work please contact Salukitech for more assistance.
