Using a YubiKey Hard Token to Authenticate with MFA

The hard token is an alternative method for those who are unable to use the Authenticator app or other phone options for multi-factor authentication. To get started, purchase a YubiKey hard token device from the Tech Store.

Students without a smartphone or the ability to receive text messages should create a ticket to avoid being locked out of your UARK account while waiting to receive your hard token device. 

How It Works

Once you have completed the setup steps, the YubiKey hard token device is inserted into your computer's USB drive. With the token plugged into your computer, it will automatically verify your account when logging into a UARK online service from that computer.

If you use multiple computers, you must have your YubiKey with you to use with the other computers. The Yubico Authenticator application must be installed on any computer you use to log into UARK online services.

How to Purchase a Hard Token

The university standard for hard token devices is the YubiKey provided by Yubico. These can be purchased through the University of Arkansas Tech Store by contacting Jeff Blevins at blevins@uark.edu with the YubiKey model needed for your device.  

The following YubiKey models are supported by IT Services:  

YubiKey 5 NFC (USB-A)

This is the standard-sized token, compatible with most Windows computers.

YubiKey 5Nano (USB-A)

This is a smaller-sized token, compatible with most Windows computers.

YubiKey 5Ci (USB-C and Lightning)

This token is recommended for Mac computers.

YubiKey Hard Token Setup

The YubiKey hard token plugs into your computer and verifies your UARK account for multi-factor authentication. The university recommends installing the YubiKey Authenticator app on any device you will use with the hard token. 

In order to download the application, you must have administrator access on your computer. If you are prompted for an administrator password, please contact your department's tech support person.
