Getting started with DUO security

DUO Frequent Asked Questions

  • 1. What is two-factor (DUO) and why is ASTATE implementing it?

    Passwords are becoming increasingly easy to compromise. They can often be stolen, guessed, or compromised in some other manner -- you might not even know who else has your password and is accessing your account. Duo two-factor authentication adds a second layer of security to your account to make sure that it stays safe, even if someone else knows your password, by using your phone or another device to verify your identity. You will be alerted right away (on your phone - mobile or landline - or tablet) if someone tries to log in using your password. This prevents anyone but you from accessing your accounts.

  • 2. How do I get DUO?

    ASTATE's DUO setup document makes it easy to register your phone or tablet. Install the app on your device to being the enrollment process. 

  • 3. Can I opt out of DUO?

    No. Two-factor authentication adds a second layer of security to our online accounts. In an effort to keep the university systems and your personal account information secure, we are enabling two-factor authentication on most services

  • 4. What devices can I use as a second factor with Duo?

    You can enroll and smartphone, a cell phone, a landline, a table, or a key fob. With a smartphone and a tablet, you will need to install the DUO app to receive a DUO push. IT Security recommends that you set up your device to receive a duo push. We also recommend having more than one device registered and that one of the devices be a mobile phone with the Duo Mobile app. To get a key fob you will need to contact IT Security at 870-972-3770.

  • 7. How do I enroll an additional device?

  • 9. How can I fix my DUO Authentication window that appears blank or isn’t loading correctly?

    A blank DUO box can usually be solved by one of the following steps. 

    1. Open a browser & load the website, DUO status page (ASTATE is DUO49) to look at any possible interruptions of Duo service. If you see any interruptions it means that DUO is having a system-wide outage.  If you don't see any interruptions, continue to the next step.
    2. Launch a private browser (incognito mode) right-click on your browser icon and select either incognito or private. If the screen does not load in the private browser continue to the next step. If the screen loads, open a new browser window and clear your cache and cookies. how to delete cache and cookies. 
    3. Use a mobile device and log in to the ASTATE portal if the screen will not load on the mobile device continue to the next step. If the screen loads on the mobile device it is an issue with the original device. (something lilke browser add-ons are preventing it from loading)
    4. Use a mobile device with the WIFI turned off and see if you can get the ASTATE portal to load. If the screen loads with WIFI turned off but not with it turned on then it is a WIFI issue. Either your modem or router is blocking DUO or your ISP (Internet Service Provider) is blocking DUO. If you still can not get DUO to load correctly continue to the next step.
    5. Uninstall your browser and reinstall it without importing anything in. Something in your browser is blocking the DUO box from loading. You can get Chrome or Firefox. If you can not get the box to load after this please contact IT Security at 870-972-3770.
