  • Duo Two-Factor Authentication
Skip to end of metadata
Go to start of metadata

Two-factor authentication is a second layer of security, keeping an individual's account secure even if their password is compromised. It requires two proofs of identity when logging in:

Duo provides a flexible two-factor authentication solution that allows us to extend security protection to more systems and individual accounts at U-M. With Duo, you'll be alerted right away - on any phone or mobile device - if someone is trying to log in as you.

To use Duo Two-Factor Security, and anything it protects, you'll need to enroll first. Please see the information below for instructions.

Additional Considerations for Selecting a Device
  • The device you use for two-factor will need to be with you, each time you log in to a protected service.
  • It's recommended you enroll in a primary option plus at least one backup option.
  • Where you are located while using two-factor may determine which device/options you use. The "Duo Mobile Passcode" option works without an Internet connection and/or cellular service.

If you are using two-factor for ePrescribing Controlled Substances (EPCS), see the next section for additional instructions.

Duo Self-management Options

There are a variety of features that allow you to manage your own device, authentication options, and overall Duo experience.

Manage Duo Within the U-M Two-Factor Settings Drop-down Tool (the Michigan Medicine IT User Profile Page)

  1. Navigate to the webpage: Michigan Medicine IT User Profile.

  2. Click Security Settings at the top of your User Profile. 
  3. Click U-M Duo Settings drop-down.

Verify Your Device is Connected to the Authentication Service

  • Option 1: When you access the Security Settings tab, the system may automatically start testing the device/option you selected during the enrollment process. Click cancel at the below of the window, in order to exit the testing feature.
  • Option 2: You can prompt it by clicking one of the options in the Duo account window.

Manage Your Duo U-M Two-Factor Account
This self-management Duo Two-Factor window allows you to update or change your Duo Two-Factor account settings.

Turn On/Off the UMHS Global Default Override to Set Phone Call as Your Default
Some services cannot read the current authentication options selected during the Duo Registration Enrollment process. To overcome this limitation, you must select your primary authentication option here. When a service cannot read the option/device you selected, your default is set to the Duo Mobile Push option. To override this UMHS global setting, it requires you to complete a global setting override on your profile page by selecting the Phone Call (to put the override into effect) or the Duo Push (to remove the override) radio button.

Manage Duo Within the U-M Hardware Token Drop-down Tool (Michigan Medicine IT User Profile Page)

On this page, you can do the following:

  • Add a Duo Hardware U-M Token

This process will link the token to you, which will allow it to generate a passcode when you need to use Duo.

  • Resync Your U-M Token

Sometimes hardware tokens can become out of sync with the system. If this occurs, you will not be able to login. Resyncing your token is the first line of troubleshooting, similar to restarting a computer when it doesn't work. This tool gives you the ability to resync your hardware token with the Duo Security System.

  • Remove Your U-M Hardware Token

The U-M Device is no longer associated with your name in the system.

What Special Arrangements are Made for ePrescribing Controlled Substances?

Due to DEA regulations, EPCS uses its own Duo system that's separate from everything else. Only smartphone, tablet, and hard tokens are permitted (no call back, text messaging, or temporary passcodes).

To enroll in Duo Two-Factor Security as an EPCS provider:

In either case, complete EPCS enrollment with your EPCS Liaison.

Learn More and Get Assistance

Help Me Now walk-in locations can answer your individual questions and provide you with hands on help with enrollment. (EPCS registration should be completed by the appropriate EPCS Liaison prior to visiting the Help Me Now location.) You may also return expired MTokens to any one of these locations.
