Yubikey Hardware Security Key
A hardware security key like YubiKey is a physical device that provides an extra layer of security to protect digital accounts and data. It works by requiring the user to physically insert the key into their device or tap it on a compatible device to authenticate their identity, rather than relying solely on passwords or other vulnerable forms of authentication. The YubiKey, in particular, supports multiple authentication protocols, including FIDO U2F, FIDO2, smart card (PIV), OpenPGP, and Yubico OTP. Overall, hardware security keys like YubiKey are an effective way to enhance the security of digital accounts and protect sensitive data from cyber threats.
