How to use

Once you have the Duo app installed on your smartphone, you may verify your login through a number of options. Duo will use whichever authentication method you used last by default. 

  • Push notification - Open the push notification on your smartphone, and tap Approve to log in.* 
  • Previously generated passcode - Enter the passcode, and then click Log In (see Generating Passcodes for more).
  • Passcodes via text message (Faculty and staff only) - Click Text me new codes, and receive a text message that includes a passcode. Enter your passcode on the login page, and click Log In
  • Phone call (Faculty and staff only) - Answer the call on your phone, and press 1 to log in. 

Duo will use whichever authentication method you used last by default. To choose a different method, click Other options.

* Requires Wi-Fi or mobile data connection. Duo Mobile Push uses a minimal amount of mobile data—less than 2 KB per authentication.
