Duo Two-Factor Authentication

Also known as

Also known as: 
  • Multi-Factor Authentication

ITS has partnered with Duo Security, an easy-to-use two-factor authentication system which adds an extra layer of security for faculty, staff, and students to help safeguard their data and ITS services when outside of our network. Duo allows you to use your mobile devices to provide a second layer of authentication as opposed to just the use of passwords. The video at right demonstrates how easy it is to use Duo.

Duo is available to all WCM faculty, staff, and students. You will need one of the following devices in order to register with Duo:

  • Mobile phone (highly recommended)
  • Tablet

Frequently Asked Questions

Q: What is Two-Factor Authentication?

A: Two-Factor Authentication is a security best practice that requires more than one type of security method when logging in to an application. An authentication method can include something you know (a password or PIN), or something you have (a unique code).

Two-Factor Authentication adds an extra layer of protection that makes it more difficult for anyone to gain access to your accounts, even if your password has been compromised.

Q: How will my login experience change with Duo?

A: Your login experience will only change when you are accessing a Duo protected service in a way that it determines two-factor should be invoked, such as accessing myApps from another country.

You will continue to log into the service using a CWID and password, “something you know.” Duo then, based on a policy decision, asks for the second level of authentication by utilizing a code “something you have.” The code can be easily be accessed from a smartphone app, sms, or voice call.
