Basic Notes

  • The YubiKey 5C series is a compact USB authentication device that supports multiple protocols such as FIDO2/WebAuthn, FIDO U2F, OTP (One-Time Password), OpenPGP, and smart card (PIV).

  • Yubikey devices are compatible with many ports, which are commonly found in modern laptops and smartphones.

  • By requiring a physical key to access your accounts, the YubiKey 5C series adds an extra layer of security that is far more robust than traditional username and password combinations.
