Solution

To re-assign the YubiKey to another user, please follow the steps below.

First, an MFA reset is needed for the user who previously had the YubiKey in question assigned.
Locate the Multifactor menu in the Admin Console.
Under Factor Type > select YubiKey.
Under Revoke YubiKey Seed, enter the YubiKey Serial number that needs to be re-assigned to another user and click on the Find YubiKey button. The following Prompt should be received:

Click on Delete. This will revoke and delete the key from Okta's database. However, the status will appear UNASSIGNED until the end user enrolls their YubiKey.
If one can locate the serial number in the Report or it shows as Revoke, it means the YubiKey has already been deleted from the database, and a CSV for this YubiKey that contains the serial number, public ID, private ID, and AES key needs to be manually created.
Upload the seed file again, and then it should be possible to re-assign the YubiKey to another user. Please review Enroll a YubiKey for the first time on a desktop browser.
