By far the majority of my devices have no USB Type-A port, and that's only going to be a greater annoyance as time goes on. I was also a bit miffed that neither key was USB Type-C. SMS-based verification is subject to interception and socially engineered attacks at the carrier level (i.e., someone can call in pretending to be you and change where that number points). Depending on the value of the account, the convenience of SMS verification can actually be more of a risk than a benefit. If you care about the security of an account (i.e., if it has direct or indirect access to anything you'd regret losing), then it's a good idea to enable at least some form of 2FA authentication for it, but not all methods are equal. But with USB Type-C only available via adapters, and Bluetooth/NFC support being limited to Android and iOS, for most of us it's probably a pass. But is the Titan Security Key worth your attention? If you haven't used any security keys before or if Google's customer support is important to you, then it may be worth a look. With so much of our finances, communications, and general lives taking place on remote servers, the responsibility of digital security should always be in the back of our minds, and it takes more than just a good password to stay safe.

Paired with Google's Advanced Protection Program, your account is about as secure as it can be.

Together they can provide some extra security for your Google account - as well as other FIDO U2F-compatible services. The 'Key' is actually two keys: a USB-A security key with NFC, and a battery-powered, Micro-USB-equipped Bluetooth/NFC key.
