Two-factor authentication adds a second layer of security to your online ǿմý 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).

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

  • All ǿմý employees and students can request one Duo token for free by contacting the Helpdesk. This is an alternative to using your phone, tablet or the Duo Mobile app. It will generate a passcode that you can enter when you need to complete the two-factor authentication process. The Helpdesk will assign you a Duo token and enroll it under your account. Once a token has been assigned to you, you can pick it up from the [U]Tech CARE Center in the Kelvin Smith Library. You can then use the Duo token to generate secure passcodes.
    Example of a Duo Hardware Token, which is a small device that fits on a keychain.
  • Purchasing a Duo token: The first Duo token for users is free. If you have lost your token, replacement Duo tokens can be purchased from the [U]Tech CARE Center. Faculty and staff should request a token and charge the cost to their department’s OPR code when they pick it up (Note: the Helpdesk and [U]Tech CARE Center cannot look up OPR codes--this must be presented by the user at time of pick up).
