MFA: YubiKey Facts & Purchasing Guide


This article provides basic recommendations for USNH approved YubiKeys. This article is intended for USNH faculty and staff and holds the USNH recommended MFA hardware tokens. 


IMPORTANT! The model of YubiKey previously provided by Enterprise Technology & Services, YubiKey 4, is now considered deprecated and no additional units will be distributed. These older device will not work for Salesforce authentication or in other more modern authentication environments.  See below for current versions.


Warning:  Microsoft may require a PIN when using some models of YubiKey for M365 MFA.  The YubiKey PIN is maintained through a desktop app provided by the YubiKey manufacturer called "YubiKey Manager".  Remember your YubiKey PIN or it will not work for M365 MFA.  

If you lose or forget your YubiKey PIN, you will have to work with the YubiKey "YubiKey Manager" application to reset your PIN, or work with the YubiKey manufacturer directly - ET&S has no access to assist with lost YubiKey PINs.  This is why ET&S Strongly recommends you have a secondary method set up for MFA.  See MFA: Adding Backup Multi-Factor Authentication (MFA) Methods for instructions.
