What Is a FIDO2 Security Key Card?
A FIDO2 security key card is a small device—think of it like a bank card or USB stick—that you use to log in to your accounts without typing a password. Instead, you tap or insert the key, and it proves to Google (or other services) that it’s really you. This makes it nearly impossible for hackers to break in, even if they know your password.
How Does FIDO2 Work?
- Uses public-key cryptography (no shared secrets)
- Resistant to phishing, malware, and man-in-the-middle attacks
- Can be used for passwordless, two-factor, or multi-factor authentication
Why Use a FIDO2 Security Key Card with Google?
Google supports FIDO2 security keys for all major accounts—including Gmail, Drive, and Workspace. Here’s why users and businesses are switching to FIDO2:
- Phishing Protection: Hackers can’t trick you into giving up your login.
- No More Password Hassles: Forget about password resets and complicated rules.
- Works Everywhere: Use the same key across multiple Google accounts and services.
- Meets Compliance: FIDO2 is recommended for strong security by industry standards and privacy laws.
