Two-Factor Authentication (Duo)

About Duo Two-Factor Authentication

Two-factor authentication (2FA) adds a second layer of security to your online accounts. Verifying your identity using a second factor (like your phone or other mobile device) prevents anyone but you from logging in, even if they know your password. 

The University of Cincinnati uses Duo Security for two-factor authentication.

How Duo Works

Manage Your Duo Account

Duo will push a notification to your phone asking you to approve or deny access each time you enter your UC username and password to login to a university system. Once you verify your identity on your phone with Duo, you’ll be securely logged into the system.

Most university systems require two-factor authentication with Duo to login.

Use the Duo Mobile App

The Office of Information Security (OIS) strongly recommends using the Duo Mobile App on your iOS or Android mobile device. OIS also recommends adding a second device as backup.

Choose "Send Me a Push"

Choose “Send Me a Push” in the Duo Mobile App for the quickest, most user-friendly experience. 

Use "Remember Me"

Use “Remember me” to login with Duo once (instead of…Every. Single. Time.) 

Selecting the “Remember me” checkbox tells Duo to send you one authentication request every 30 to 180 days depending on the system.

Duo’s “Remember me” feature is device and browser specific. So, if you need to use another device or browser to login, you’ll need to check the “Remember me” box again.
