Google Titan
A hardware security key by Google for phishing-resistant FIDO2/WebAuthn authentication.
What is Google Titan?
Google Titan is a hardware security key developed by Google that provides phishing-resistant authentication via FIDO2/WebAuthn standards.
Titan Key features:
- FIDO2/WebAuthn: Passwordless authentication (not just second factor)
- NFC + USB: Works with mobile (NFC tap) and desktop (USB-A or USB-C)
- Google Advanced Protection: Required for Google's strongest security program
- Tamper-resistant: Private keys stored in secure element (can't be extracted)
Titan comes in two models:
- Titan Security Key (USB-A): Traditional USB-A connector
- Titan Security Key (USB-C): Modern USB-C connector
Titan is essentially a rebranded YubiKey (manufactured by Yubico for Google) with Google-specific firmware.
Analogy
Think of Google Titan like a house key made by a locksmith (Google). It works with your door (computer) and can't be duplicated. Even if someone steals your password, they can't copy your Titan key - it uses cryptography that stays inside the device.
Types and Use Cases
- "Google Advanced Protection: Required for Google's strongest security program"
- "Enterprise SSO: Use Titan for phishing-resistant employee authentication"
- "Consumer: Use Titan for personal Google, Facebook, GitHub accounts"
- "Banking: Use Titan for PSD2 Strong Customer Authentication"
How it Works
// FIDO2/WebAuthn with Titan Key
const assertion = await navigator.credentials.get({
publicKey: {
challenge: new Uint8Array(32), // from server
allowCredentials: [{
type: "public-key",
id: titanCredentialId,
transports: ["usb", "nfc"] // Titan supports both
}],
userVerification: "required"
}
});
// Titan signs challenge with private key (never leaves device)
// Server verifies signature using public keyGoogle Titan vs YubiKey

YubiKey
Google Titan is rebranded YubiKey (manufactured by Yubico)
YubiKey has more models (5 NFC, 5C, Bio)
Titan only supports FIDO2/WebAuthn
YubiKey also supports Yubico OTP, Smart Card, OTP
Titan is Google-branded
YubiKey is Yubico-branded (broader compatibility)
Best Practices for Google Titan
- "Register 2+ keys: Always have backup Titan key in case primary is lost"
- "Use FIDO2 (passwordless): Don't just use Titan as 2FA - use it for full passwordless login"
- "Require touch: Set userVerification to 'required' - Titan won't sign without physical touch"

LoginRadius handles the complete WebAuthn flow, provides fallback authentication methods (TOTP, SMS) for lost keys, and offers detailed FIDO2 analytics and audit logs for compliance.
FAQs
Google Titan is manufactured by Yubico for Google - it's essentially a rebranded YubiKey 5. YubiKey (by Yubico) has more models (5 NFC, 5C, Bio, FIPS) and supports more protocols (Yubico OTP, Smart Card, OTP in addition to FIDO2). Titan only supports FIDO2/WebAuthn. Functionally, they're nearly identical.
Yes, Google Advanced Protection Program requires either: (1) Titan Security Key, or (2) YubiKey (any FIDO2-compliant key). Advanced Protection provides strongest security: no password recovery via phone/email, only hardware keys work. Titan is Google's branded option, but any FIDO2 key works.
LoginRadius fully supports Google Titan (and all FIDO2 keys) via WebAuthn/ FIDO2 integration. Our platform handles Titan registration (USB or NFC), authentication (sign challenge), and credential management. LoginRadius supports Titan for both passwordless login and MFA. We also provide fallback methods (TOTP, SMS) if Titan is unavailable, and detailed FIDO2 audit logs.
