Exploring FIDO2 Passwordless Authentication: Benefits and Easy Implementation for Businesses

February 6, 2025

Have you heard of FIDO2 Passwordless Authentication? This advanced identity verification technology is quickly becoming a favorite in the cybersecurity industry. More than just a security trend, it’s also a game-changer in improving user login experience. In this article, we’ll explore the significant business benefits of FIDO2, and demonstrate how easy it is to implement HiTRUST's Veri FIDO solution for your organization.

Challenges and Risks of Traditional Passwords

In the digital age, "login" is a very common operation, but it is also a key link that affects user experience, network security, conversion rates and corporate reputation.

Password-related issues have led to lower user satisfaction with many companies.

Users abandoned checkout processes due to forgotten passwords and redirected platforms.

Security incidents and fraud come from the leakage of accounts, passwords, and credentials.

Phishing emails have grown rapidly post-Covid.

What is FIDO2 Passwordless Authentication?

FIDO2 is a new generation of authentication standards launched by the Global FIDO Alliance, with the goal of replacing traditional passwords and addressing various issues associated with them. When users log in to websites or mobile apps, they can use biometric authentication or a device PIN to activate the security key within their device, enabling secure identity verification without the need for a password.

How Does It Work?

FIDO2 consists of the following two key components:

  • 1. WebAuthn (Web Authentication API)
    WebAuthn, jointly developed by W3C and the FIDO Alliance, is an API that enables websites to seamlessly communicate with the authentication parties (Relying Party or RP).

  • 2. CTAP (Client to Authenticator Protocol)
    CTAP is used to connect a user's device (such as a smartphone or computer) with a website or app, allowing the authentication process to work smoothly across different devices.

What is the difference between FIDO2 and general biometrics?

Traditional biometric authentication commonly involves using facial recognition or fingerprints to unlock previously stored passwords, offering a convenient way to remember them. However, passwords still exist and are transmitted, which makes them vulnerable to attacks such as phishing, credential stuffing, and man-in-the-middle attacks.

The secret weapon of FIDO2 lies in public key cryptography, which generates a pair of keys when the user registers:

  • The public key is stored on the FIDO2 server.

  • The private key is securely stored in the user's device, and the information is not transmitted elsewhere.

With FIDO2, the private key is safely stored on the user's device, and their biometric information or PIN code is only utilized on that device. Hackers cannot steal any important, personal data even if they attack the website's server.

FIDO2 Benefits: Why is it Good for Business?

Comprehensive Upgrade for User Experience

Have you ever thought that customers might leave your platform due to forgotten passwords? Traditional passwords not only cause inconvenience for users but can also increase the bounce rate of your site. According to Google's user behavior report, platforms using FIDO login see login success rates improve by up to four times! FIDO2 enables users to log in using familiar biometric authentication, creating a quick and seamless experience that significantly boosts conversion rates and user satisfaction.

A Defense Against Modern Cybersecurity Threats

Passwords are hackers' most favorite target and data breaches involving passwords are increasingly common. FIDO2's architecture is specifically designed to combat these cyber threats, being the only authentication method that can defend against phishing, man-in-the-middle attacks, and completely eliminate password vulnerabilities. This enhances security for both businesses and users.

Reduced Operational Costs

Businesses spend a significant amount annually on password management. In the unfortunate event of a cyberattack, in addition to the customer service handling costs, media exposure can also damage the company's reputation. By implementing FIDO2, businesses can eliminate costs associated with creating password management policies, dealing with forgotten passwords, resetting passwords, and SMS OTPs, freeing up more resources for other business growth areas.
