We strongly recommend enrolling at least two devices in MFA with Duo so you always have a method of authenticating, even when you can't use your primary method. Many options are available, so most people should be able to find two methods that work for them.
If you plan to use the Duo Mobile app with a smart device:
Enroll a Smartphone or Tablet via the Duo App - Smartphones are the easiest and most popular method of enrolling in Duo. Authenticating with your smartphone is quick and works with or without a WiFi or SMS connection. You can also authenticate with a smart device, such as a tablet.
Once you have enrolled your smartphone or other device, set your notification preference to:
- Send Me a Push - Duo sends an authentication request to your smartphone or device, you tap Approve, and you're in. This uses internet or cell connection and is the fastest method to authenticate. Watch a short YouTube video about how to use Duo push notifications.
If you do not use a smartphone nor plan to use the app:
Enroll a Hard Token - A hard token is a keychain device that generates a passcode that you enter when you are authenticating with Duo. It does not require an internet or phone connection. You select the Enter a Passcode option and then type in the passcode that is displayed on your hard token. You can request a hard token by calling IT Services at (805) 893-5000 (x5000).
