Titan Security Key
What it is
Titan Security Key is a physical key designed to help prevent phishing and keep unauthorized people out of online accounts, including Gmail. Current USB-A and USB-C models support NFC. Google-engineered firmware checks the key’s integrity, while a purpose-built secure element is designed for high-assurance security products. The keys use FIDO open standards and work with Google, Google Cloud, and other services supporting FIDO CTAP1. They are compatible with Google’s Advanced Protection Program. Computer use requires USB and a current browser supporting W3C Web Authentication, including Chrome, Firefox, Opera, Edge, and Safari; Google lists Windows 10 build 1903 or later for USB use. NFC works on compatible Android 9 or later and iOS 13.3 or later devices. Compatible Android devices can also use USB, while iPads with iOS 13.3 or later have USB support but no NFC. The listed plan is $30, paid once, with free shipping.
