Which Devices Should I Enroll in MFA with Duo?

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. 

You have several options available if you have enrolled your smartphone or other device:

  • 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
  • Enter a Passcode - The Duo app on your smartphone or device generates a code and you type it in. This method does not require an internet or cell connection.
  • Text Me - The Duo app sends you an SMS text message. This method requires cell connection.

If you do not use a smartphone nor plan to use the app: 

Enroll a Cellphone via SMS - If you enroll a cellphone via SMS, you authenticate using the Text Me option. You will receive an SMS to authenticate your identity.

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 the IT Services Catalog at (805) 893-5000 (x5000).
