What is Duo?
Duo is Maricopa Community Colleges’ two-factor authentication service providing an extra layer of security to protect against hackers, cyber threats, and any unauthorized access to sensitive data.
An added security measure, two-factor authentication is now a federal requirement under the Gramm-Leach-Bliley Act (GLBA), ensuring the protection of student data.
Beginning May 23, 2023, all student applications will require Duo two-factor authentication when logging in to password-protected systems. If you have a smartphone, it is recommended that you use the Duo Mobile app to authenticate, as it offers the easiest and most secure method of two-factor authentication.
If you are a student at one of the Maricopa Community Colleges and you have not yet signed up for Duo, please log in to the Student Center, where you will be prompted to set up two-factor authentication.

What Is Two-Factor Authentication?
Two-factor authentication is a safe and secure way for you to access your online accounts—keeping your data protected from remote cyber attacks. When you are asked to “authenticate,” you are being asked to verify your identity.
An Introduction to Duo Security
Two-factor authentication is a safe and secure way for you to access your online accounts—keeping your data protected from remote cyber attacks. When you are asked to “authenticate,” you are being asked to verify your identity.
Options for Using the Duo Service
There are several options for using the Duo service depending on your needs and preferences. You can stay safe and secure whether you authenticate (i.e. verify your identity) via smartphone, landline, or flip phone. Select the method/device that works best for you.
If you have a smartphone, we recommend using the Duo Push mobile app method, as it offers the easiest and most secure two-factor authentication.
Duo Push Mobile App
We recommend using Duo Push as your primary method to authenticate. Duo Push, the Duo mobile app, is the easiest, most convenient, and most secure way to set up two-factor authentication and use it daily. You can download Duo Push right from your smartphone.
How it works: Duo will send you a “push” notification every time you are prompted to authenticate. The Duo app also provides an alternative authentication method by way of generating a passcode if Wifi and cell signal are not available.
If You Don't Have a Smartphone
If you don’t have a smartphone, there are programs available to help you procure one. One such resource is Lifeline, a federal program that provides free cell phones to Americans who fall below certain income thresholds.
The preferred and most secure method of using Duo two-factor authentication is with a smartphone and Duo app that supports iOS/Android phones (Apple Store or Google Play). However, you can also use an iOS/Android tablet, non-smartphone, and landline.
How it works: Duo will send you a “push” notification every time you are prompted to authenticate. The Duo app also provides an alternative authentication method by way of generating a passcode if Wifi and cell signal are not available.
If you do not have one of these devices, we have a limited supply of security keys that are available only to students in need. To pick up a security key, students should visit the following campus locations:
