It requires the use of your smartphone, however, which is not only inconvenient, but can be a problem if your phone is lost or breached. Hardware security keys can offer an additional layer of security to password-protected online accounts and, in turn, your identity. They’re also not hard to install. Here’s how to set them up for your Google account, Facebook, and Twitter.
When you insert a security key into your computer or connect one wirelessly, your browser issues a challenge to the key, which includes the domain name of the specific site you are trying to access. The key then cryptographically signs and allows the challenge, logging you in to the service.
Many sites support U2F security keys, including Twitter, Facebook, Google, Instagram, GitHub, Dropbox, Electronic Arts, Epic Games, Microsoft account services, Nintendo, Okta, Reddit, and many more.
