Damn these some real pro tips. I had to read up on the Yubikey from your last post. What would you use the Yubikey for though? To protect your computer? I don't keep my
better explaination of a Yubikey
The
YubiKeys are among the most popular security keys. Some YubiKey models have a wide range of features such as:
Universal 2nd Factor (U2F),
FIDO2 and WebAuthn,
Yubico OTP,
Personal Identity Verification (PIV),
OpenPGP,
TOTP and HOTP authentication.
One of the benefits of the YubiKey is that one key can do almost everything (YubiKey 5), you could expect from a hardware security key. We do encourage you to take the
quiz before purchasing in order to make sure you make the right choice.

The
comparison table shows the features and how the YubiKeys compare. We highly recommend that you select keys from the YubiKey 5 Series.
YubiKeys can be programmed using the
YubiKey Manager or
YubiKey Personalization Tools. For managing TOTP codes, you can use the
Yubico Authenticator. All of Yubico's clients are open source.
For models which support HOTP and TOTP, there are 2 slots in the OTP interface which could be used for HOTP and 32 slots to store TOTP secrets. These secrets are stored encrypted on the key and never expose them to the devices they are plugged into. Once a seed (shared secret) is given to the Yubico Authenticator, it will only give out the six-digit codes, but never the seed. This security model helps limit what an attacker can do if they compromise one of the devices running the Yubico Authenticator and make the YubiKey resistant to a physical attacker.
Warning
The firmware of YubiKey is not open source and is not updatable. If you want features in newer firmware versions, or if there is a vulnerability in the firmware version you are using, you would need to purchase a new key.
