However, YubiKey has better support for SSH authentication compared to Google Titan. And just like YubiKey, Titan keys also offer cryptographic proof that users are interacting with legitimate services once they have registered their security keys. The Titan hardware chip includes firmware to help verify that the keys haven't been tampered with. Titan security keys are compatible with the Advanced Protection Program, Google's strongest account security program, originally introduced to safeguard politicians, journalists, activists and others who are at a high risk of targeted online attacks, but now available to everyone. Google Titan is also a hardware security key, developed by Google, and can be used to authenticate to Google, Google Cloud, and many other services that support FIDO standards. Source: How is YubiKey Different from Google Titan? The most popular YubiKeys are USB-A/NFC, USB-C/NFC and USB-C/Lightning. The keys are IP68 rated, crush resistant, with no batteries or moving parts, making them really ideal for long term use. YubiKey supports multiple authentication protocols, including U2F, FIDO2/WebAuthn, OpenPGP, OTP, and smart card, and ships in USB-A/C, NFC and Lightning form factors.

YubiKey is a hardware security key from Yubico, providing strong multi-factor authentication for a wide range of applications and services. In this post, we'll do a deep dive into YubiKey security keys, common authentication use cases, and interacting with the devices programmatically during FIDO2 registration and authentication. FIDO2-based hardware security keys like Google Titan and YubiKey are probably the only known phishing resistant technologies available today. Legacy MFA schemes like PIN, SMS/Email OTP, TOTP apps, and mobile push, are vulnerable to phishing attempts and malware.
