ieq6b (ieq6b) asked a question.
I reset multifactor on an account. Now the Yubikey is blocked from use. How do I reset the Yubikey so I can use it again?

I've played with Yubikey a bit and encountered this very issue, but not 100% recalling the exact cause and fix.
As you likely know, you have to upload a seed/secret file to Okta of your Yubikeys. I think resetting MFA for a user isn't enough to reuse the token again. I believe you must upload an updated seed/secret file.
For general reference:

You can use the key by uploading yubikey (.csv file) from "Upload YubiKey Seed File" in Yubikey configuration
You can revoke from below
Enter Yubikey serial number
Find Yubikey
Delete
