Duo Security Overview

Duo Security Overview

Quickly and simply configure DUO security 2-factor authentication for use with your cell phone, landline, smartphone, tablet, laptop or hardware token.


Two-factor authentication adds a second layer of security to your online CWRU accounts. Verifying your identity using a second factor (like your phone or other mobile device) prevents anyone but you logging in, even if they know your password.

For more help, call the Service Desk at (216) 368-HELP (4357).


Recommended Equipment

Self enrollment is available via multiple methods. Information Security recommends all users enroll the following two devices:

  • Smartphone using the mobile application for iOS or Android
  • Desk phone (landline) using the voice call method


IMPORTANT UTech Information Security recommends you use your desk phone as a backup in the case that a mobile phone is lost, stolen or damaged.

However, Case Duo lets you link multiple devices to your account, and you may use any combination of compatible devices to secure it.

Enroll an Authentication Device in DUO Security

Case Duo supports a range of electronic devices including;

  • iOS smartphones and tablets
  • Android smartphones and tablets
  • Blackberry devices
  • Windows phones
  • Basic cell phones with and without text msg capabilities
  • Landlines
  • Hardware tokens (e.g., Yubikey - enrolled by administrator)


Authenticate with a Supported Device

Review the table below to identify what methods of authentication your enrolled devices support. Then, follow the instructions to authenticate a VPN session.

Notes for Multi-Device Accounts

It's possible to call or send SMS codes to any compatible device in your profile by typing "PHONE" or SMS" and its number in series (e.g., "SMS2", "PHONE2") in the Second Password box.

However, if you use the Manage Devices screen to change the order of your devices so that your basic cell phone appears before your your smartphone (but after any landline) you'll not need to remember the order of devices to authenticate by the preferred method when using a multi-device account.

Also, if you use the mobile application with both a smartphone and tablet, the device you'll use to authenticate more often should appear first.

Because hardware tokens are not associated with a phone number, it does not matter where in the order of devices they appear.

To access the Manage Devices screen, first enroll at least one device. The enrollment page now features a gray button marked Manage devices. Click this and then authenticate. The management screen opens after successful authentication.
