Launched by Google in August last year, Titan Security Key is a tiny low-cost USB device that offers hardware-based two-factor authentication (2FA) for online accounts with the highest level of protection against phishing attacks.
Titan Security Key, which sells for $50 in the Google Store, includes two keys—a USB-A security key with NFC, and a battery-powered, Micro-USB-equipped Bluetooth/NFC key—for secure two-factor authentication.
