Thetis Pro FIDO2 Security Key USB-A USB-C NFC

Designed for people and organizations that want stronger account protection without relying solely on passwords, the Thetis Pro supports FIDO2/WebAuthn, U2F, TOTP/HOTP authenticator functions and PIV certificates. It fits on a keyring or stays plugged into a workstation, works with most major online platforms, and adds an optional complex PIN layer called PinPlex for extra physical-key security.

How does Thetis Pro make logging in faster and more secure?

Thetis Pro replaces or augments passwords by using public-key cryptography and device-bound credentials. With NFC for mobile and USB-A/USB-C for desktops, it enables quick, phishing-resistant passkey or 2FA interactions while PinPlex protects the key itself with a complex PIN scheme.

• Supports FIDO2/WebAuthn and U2F for passwordless or second-factor logins.
• NFC for touch-to-authenticate on phones, USB-A/USB-C for laptops and desktops.
• PinPlex adds a hardware-level complex PIN to prevent unauthorized use.

Which platforms and services will work with this security key?

Thetis Pro is FIDO-certified and interoperates with many major providers that accept FIDO2 or U2F tokens. Compatibility varies by service and browser—check the specific provider for their FIDO2 support and any platform caveats.

• Designed to work with Google, Microsoft, GitHub, Dropbox and other FIDO-supporting services.
• Chrome login support across Windows versions; Windows Hello requires Enterprise with Entra ID.
• Not compatible with ID Austria’s FIDO2 Level 2 requirements.

What authentication modes and extras does it offer?

Beyond FIDO2 passkeys and U2F, Thetis Pro includes TOTP/HOTP authenticator functionality and PIV certificate support for organizations that need smart-card-style identity. You can use the device as a one-stop token for multiple authentication workflows.

• TOTP and HOTP generation lets the key act as an authenticator app substitute.
• PIV certificates enable enterprise-style identity and secure access control.
• PinPlex adds an optional PIN layer to harden physical access to the key.

How do I carry and use the key day-to-day?

Thetis Pro is built for everyday carry and desktop use. Plug it in, tap for NFC, or keep it on a keychain—usage is straightforward and fast, with options for plug-and-stay or portable authentication when on the move.

• Dual USB-A and USB-C connectors for broad device compatibility.
• NFC for quick mobile authentication without cables or adapters.
• Compact form factor fits keyrings and remains available when needed.

Who is this for? The Thetis Pro is aimed at security-conscious individuals, IT teams and organizations that require flexible multi-factor and passkey options. It suits professionals who need cross-platform compatibility—desktop, laptop and mobile—plus extra hardware PIN protection and enterprise features like PIV and TOTP/HOTP. If you want a single security token to cover passwordless logins, standard 2FA, and corporate smart-card workflows, Thetis Pro is built to be a versatile, portable solution. Verify your service or platform’s FIDO support and any special requirements (for example, Windows Hello Enterprise with Entra ID) before deploying across an organization.
