Compact and effective
I'm an Internet Engineer, and I've been building infrastructure for media companies for nearly 25 years. I know firsthand that companies don't care about your data as much as they care about saving money, so protecting yourself is up to you.Google issued hardware keys like this one to all of their employees, and after doing so, they were immune to phishing attacks. If you want to be sure that the hackers behind the next data breach can't access your accounts even if they get your password, then a U2F key is the way to go.U2F keys activate the "something you have" of two-factor authentication, complementing the "something you know." There are a number of ways to deliver 2FA - authenticator apps with one-time passwords, text messages or emails with codes in them, RSA-style dongles with the six digits that change every minute, or a U2F key like this. The nice thing about a U2F key is that it _complements_ another form of 2FA. If you don't have your phone with you or left your RSA dongle at home, having a U2F key on your keychain means you can still access your accounts, and vice versa. You can even activate multiple U2F keys, whereas sites only allow a single OTP or authenticator app.Always have a backup for important things.I set it up with Dropbox and Google Apps, and it only took a moment. This key is small enough to go unnoticed on my keyring, and I like that it folds to protect the USB connector. I have another key from a different vendor that doesn't offer protection for the connector, and I'm concerned about how long it will last, flopping around in my pocket. The key from Thetis feels solid, and I'm glad that I bought it.How small is it? I've added a couple of pictures to show you how it looks with a USB-C adaptor in my Mac, a pair of AirPods, and a standard folding-style USB flash drive. It's tiny.Support for U2F is new, but as more sites recognize that they can protect their users by enabling support for it, it will become more prevalent. I recommend that you pick one of these up and activate it everywhere that you can.
