Hardware security keys that replace SMS codes, shipped from Sydney with advice on which one actually fits your setup.

Security Key Series

The rollout key. FIDO2 and WebAuthn only, which is everything a Microsoft 365 or Google Workspace sign-in needs, at about half the price of a 5 Series. Start here unless something below says otherwise.

YubiKey 5 Series

Adds smart card, OATH codes, OpenPGP and Yubico OTP on top of FIDO2. Worth the difference for admins, break-glass accounts and anyone whose password manager or VPN needs more than WebAuthn.

YubiKey Bio Series

A fingerprint instead of a PIN. FIDO2 and WebAuthn only, like the Security Key Series, so you are paying for the sensor rather than extra protocols. Built for shared desks where typing a PIN in the open is the problem.

YubiKey 5 FIPS 140-3 Series

The 5 Series in a NIST-validated build to FIPS 140-3, the current federal standard. This is the version to specify on new procurement: the older 140-2 generation is being retired. Registering a key voids change-of-mind returns.

YubiKey 5 FIPS 140-2 Series

The earlier FIPS validation, kept only where a control set still names 140-2 specifically. For anything new, choose the 140-3 series above. Registering a key voids change-of-mind returns.

YubiKey HSM

A hardware security module for servers, not a login key. It protects private keys — a certificate authority, code signing, database encryption — inside dedicated tamper-resistant hardware. Installed in a server, not carried on a keyring.
