MFA-Duo - Accessibility & Usability Information

This document details MFA-Duo specific usability and accessibility information including known issues, functional workarounds and how to get help.

Multi-Factor Authentication (MFA) is a second login step after NetID login. This extra step helps to protect both your online identity and UW–Madison digital assets. MFA is continuously evaluated for usability and accessibility. Below are the accessibility and usability known barriers, functional workarounds, and how to get help. To view a listing of all MFA devices and features see MFA-Duo Device Options.

Accessibility and usability barriers: Token/Fobs are less usable

People with blindness or low vision may not be able to read the passcode on the Duo or OTP c100 token/fobs because:
  • the passcode characters are small the screen is not backlit
  • the expiration time for the passcode entry is short 
Additionally, the screen orientation is not clear, making it easy to input the passcode upside down. Users with motor impairments, tremors, or dexterity limitations may be unable to press and hold the button long enough to generate a passcode. 

Token/fobs can also get out of sync and stop working. This occurs when the user presses the button multiple times while not in the process of logging in. (See What if my token/fob stops working for more details.) 

More accessible options: 

Feitian USB Security Key (Desktop/Laptop users) 

For people who have difficulty using a token/fob, UW–Madison offers a device called a Feitian USB security key. This allows users to authenticate by inserting the security key into the USB port of their computer or laptop.

Duo Security Mobile App (smartphone/tablet users)

The Duo mobile app allows users to login to MFA using a randomly generated security code, or approve login via a push notification.
