If you don&#x27;t trust the computer you are signing in from don&#x27;t use a YubiKey or any other token.<p>Tokens are fine to ensure that credentials cannot be easily compromised and to provide 2FA.<p>PED security is really critical when the goal is to duplicate the token e.g. credit cards if your machine is compromised then any data protected by the Token can also be compromised as soon as you access it.<p>When in doubt wipe, while it&#x27;s nice to have a robust security stance in this case I don&#x27;t think i would matter much.
