What is Duo Mobile?

Auburn University uses Duo Security for multi-factor authentication (MFA) to verify identity during login using a physical device. The physical device may be a smartphone or tablet using the Duo Mobile app, a text message to a cell phone, an automated voice call to a landline or cell phone, or a Duo hardware token. Users are encouraged to register at least two devices for backup. The Duo Mobile app is the recommended method for multi-factor authentication.

Duo Frequently Asked Questions


I am a retiree. How do I access the VPN?

If you are a retiree and need to access the VPN, you will need to set up Duo. Once Duo is set up, visit aub.ie/vpnkb for Global Protect VPN instructions.

I have received a push notification, text message, or phone call through Duo that I did not initiate. What should I do?

This may be an attempt to compromise your account. Do not accept the push, text, or call. It is recommended that you change your password through My Account and notify the IT Service Desk at (334) 844-4944.

Why am I not receiving the Duo push notification?

Assuming you have configured your device to receive Duo push notifications and have installed the Duo mobile app, you may need to power cycle your device to ensure it is functioning properly. On rare occasions, iPhone and Android devices may not display the Duo push notification; however, a power cycle usually resolves this issue.

If you have a replacement phone with the same number and your Duo Mobile app is disabled, refer to the Knowledge Base article: Reactivating Duo Mobile for self-reactivation instructions or contact the IT Service Desk at (334) 844-4944.

MFA Fatigue


With cybercrime on the rise, more organizations are implementing best practices such as multi-factor authentication to protect their users from credential theft, phishing attempts, and brute-force password guessing. To get around this added layer of protection, hacking groups have developed a new tactic: MFA fatigue. MFA fatigue relies on spamming victims with endless authentication prompts until they grant the attacker access by accident or out of sheer frustration.

If you receive repeated MFA prompts that you did not initiate, do not accept the prompts. Instead, deny the requests and report it as suspicious using the Duo app.

If you have any concerns regarding your Duo account, please contact the IT Service Desk at (334) 844-4944.
