2 step verification is the easiest way to add more security to your sensitive accounts. Search engine giant Google added 2-step account Verification to the next level with Physical Security Key.
The security key works as a physical device that will verify the accounts you’re logging into are genuinely connected to Google.
Google says 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.
