If you’ve been logging in with Duo the same way for awhile, now is a good time to review your options and consider whether there are other methods that might work better for you. 

Duo Mobile app

Advantages:

  • Offers multiple login-approval methods (passcode, push notification; phone call and text message when installed on a smartphone).
  • Works with or without a WiFi or cellular connection.
  • Likely always with you because it is stored on your smartphone or tablet.
  • Works with Apple Watch and Android smartwatch.
  • When traveling internationally, most people can use the Duo Mobile app to generate a passcode because it works without a WiFi or cellular connection.

Considerations:

  • Requires a smart device.

Text message

Advantages:

  • Each text message contains 10 passcodes that are good for 30 days.

Considerations:

  • Requires a WiFi or cellular connection to receive a text message; standard text message rates apply.

Hardware token

Advantages: 

  • Key fob is small and easily attached to a keychain, backpack, and so on.
  • Available at no cost to individuals from the Computer Showcase.

Considerations:

  • May be lost or misplaced. You are responsible for the cost if you want a replacement.

YubiKey

Advantages:

  • Fits in the USB port of your computer, so login is quick and easy. Just touch the YubiKey.
  • Available at no cost to individuals from the Computer Showcase.

Considerations:

  • Takes up USB slot.
  • Not a good option if you use multiple computers.

Phone call

Advantages: 

  • You can use any or all of your phone numbers, including your U-M phone, personal home phone, and cell phone.
  • Tip: Your university phone number is a good backup option if you forget a device at home.

Considerations:

  • If you use a shared phone at work, you need to be at the phone to answer the call when you are logging in. Only you can verify your login.
  • Requires a phone—landline or cellular; standard phone rates apply.

And remember, be sure to set up a backup option if you haven’t done so already! See Options for Two-Factor Authentication for descriptions of all the options with links to enrollment procedures.
