Security breaches and phishing attacks are still distressingly common these days, so many of us secure accounts through two-factor authentication (2FA) systems based on SMS or Google Prompt. That's better than nothing, but 2FA codes might not be enough for high-risk individuals. Physical 2FA devices add another layer of security, and Google made available to the general public last year its Titan Security Key Bundle. Initially released with USB-A, NFC, and Bluetooth support, the 2019 edition of Titan has now been updated to support USB-C natively.
