FIDO U2F Authentication, or Universal 2nd Factor Authentication, is a specific FIDO-compliant authentication method that enhances security by requiring users to present a physical security key as the second factor during login.

It is commonly used to protect online accounts and services.

What are the Key Features of FIDO U2F Authentication?

  • Physical Security Key: Users must possess a physical security key, such as a USB key or NFC-enabled device, to complete the authentication process.
  • Two-Factor Authentication: U2F is a form of two-factor authentication (2FA), as it combines something the user knows (e.g., a password) with something the user has (the physical key).
  • Phishing Resistance: U2F is highly resistant to phishing attacks because it requires the user to physically interact with the security key, making it difficult for attackers to replicate.
  • User-Friendly: U2F is considered user-friendly because it simplifies the authentication process and reduces reliance on passwords.
  • Strong Security: The use of a physical key provides robust security, as it is challenging for attackers to compromise remotely.

Conclusion

FIDO U2F Authentication is widely adopted by online services, including email providers, social media platforms, and financial institutions, to enhance the security of user accounts. Users can easily incorporate U2F keys into their login routines for added protection.
