Overview
What is Duo Security?
Duo security is a multi-factor authentication tool that allows enrollees to protect their EMU accounts from compromise, even if your password is stolen. Much like your ATM PIN and ATM card, Duo makes use of "something you know" like your password and "something you have" such as your phone. Even if your password is stolen, cybercriminals cannot access your Duo protected services without access to your phone.

Additionally, you cannot take a Duo hardware token with you. Both Duo Mobile and the hardware tokens use cryptographic technology that is subject to Federal export control regulations. While in one of these embargoed countries, use a phone call or passcodes retrieved using SMS to authenticate with Duo. Contact the Office of Research Compliance (7-3090) if you have questions.

Request the token several days in advance of your departure and then return it to I.T. when you return to the U.S. so we can re-use the device for other travelers.

What if my Duo token stops working?
If the token no longer displays numbers when the green button is depressed, please submit a help request to the Help Desk explaining the issue.
If the token still displays the number, but the code doesn't seem to work, the token may need to be reset. If your code does not work, please try again with a different code, then again with a different code, up to four times, to resynchronize your token. Do not use the same code twice or you'll need to start over.

How can I use a landline as my second factor with Duo when I'm using VPN?
If you only have your landline enrolled the VPN will use it by default.
If you have a mobile phone with Duo push this will be preferred automatically over the landline. If you want to use your landline instead you can append the device after your password when logging into the VPN. Usually this would be phone2, so input password,phone2 (with the comma and without spaces) to receive a voice call.
Alternatively, you could temporarily unenroll your smartphone and re-enroll it later when you have it available.
Can I "opt-out" of using Duo?
No. All EMU employees and students are required to enroll in Duo Security.
I don't always have my phone / device with me.
We suggest that you enroll as many devices as you wish. You can enroll your phones, tablets and even security tokens so that you have a high probability of having at least one of those devices available for authentication when needed.
If you have any other questions about Duo, submit a Service Request and we will be happy to assist you.
