2-Step Verification offers a strong extra layer of protection for Google Accounts. Once enabled, you’re asked for a verification code from your phone in addition to your password, to prove that it’s really you signing in from an unfamiliar device. Hackers usually work from afar, so this second factor makes it much harder for a hacker who has your password to access your account, since they don’t have your phone.
Today we’re adding even stronger protection for particularly security-sensitive individuals. Security Key is a physical USB second factor that only works after verifying the login site is truly a Google website, not a fake site pretending to be Google. Rather than typing a code, just insert Security Key into your computer’s USB port and tap it when prompted in Chrome. When you sign into your Google Account using Chrome and Security Key, you can be sure that the cryptographic signature cannot be phished.
Security Key and Chrome incorporate the open Universal 2nd Factor (U2F) protocol from the FIDO Alliance, so other websites with account login systems can get FIDO U2F working in Chrome today. It’s our hope that other browsers will add FIDO U2F support, too. As more sites and browsers come onboard, security-sensitive users can carry a single Security Key that works everywhere FIDO U2F is supported.
Security Key works with Google Accounts at no charge, but you’ll need to buy a compatible USB device directly from a U2F participating vendor. If you think Security Key may be right for you, we invite you to learn more.
