Result #

1. Update Yubikey Firmware #

It is not possible to update any Yubikey’s to the latest version: YubiKey Firmware is Not Upgradeable.

It is possible to find the current version using this guide: Where to find YubiKey Firmware Version.

Note: Quick and dirty command; assuming you have yubikey-manager installed: ykman info.

2. Factory Reset YubiKey #

I compiled all the information within this documentation: Factory Reset Components.

Note: Non-Resident SSH Keys will be stored in FIDO Component.
