☝ Hardware security keys like YubiKey provide an extrasecure level of twofactor authentication.

☝ How does a YubiKey work?
After associating a hardware security key with your online account, you’ll be asked to provide it later if twofactor authentication is required. These keys operate by provided securely encrypted onetime information that can be confirmed as authentic by the online service, proving you are who you say you are, or that you at least are in possession of the proper security key.
