What is FIDO (FIDO)?

FIDO, which stands for Fast IDentity Online, is an open standard developed to enhance online authentication security while improving user experience. Launched in 2013, FIDO aims to reduce reliance on passwords, which are often vulnerable to theft and misuse. The FIDO Alliance, a consortium of industry leaders, created protocols for secure, passwordless authentication methods using biometrics, hardware tokens, and other technologies. These protocols, including FIDO U2F (Universal 2nd Factor) and FIDO2, enable users to authenticate using their devices in a secure manner, making online systems more resilient to phishing and account takeovers.

Who are the Founders of FIDO?

The FIDO Alliance was founded by a group of technology companies in July 2012. Key founding members include:

• PayPal
• Google
• Microsoft
• Intel
• Yahoo!

Since its inception, the alliance has grown to include over 300 organizations, including security firms, hardware manufacturers, and software developers, all working collaboratively to enhance online security standards.

How does FIDO Work?

FIDO operates on a public key cryptography system that eliminates the need for shared secrets like passwords. Here’s a simplified overview of how it works:

1. Registration: When a user registers with a FIDO-enabled service, a unique key pair is generated on the user's device. The public key is sent to the server, while the private key remains securely stored on the device.
2. Authentication: To log in, the user initiates authentication on the service. The server challenges the user device to prove possession of the private key, typically through a biometric scan (like a fingerprint) or a hardware token.
3. Response: The device signs the challenge with the private key and sends it back to the server. The server then verifies the signature against the stored public key. If the verification succeeds, the user is authenticated.

This process ensures that sensitive information, such as passwords, is never transmitted or stored, significantly enhancing security.

Top Use Cases of FIDO

FIDO has a wide range of applications across different sectors. Here are some of the top use cases:

• Banking and Financial Services: Banks use FIDO for secure transactions and account access, reducing fraud and enhancing customer trust.
• Healthcare: Healthcare providers implement FIDO to secure patient data access, ensuring compliance with regulations like HIPAA.
• eCommerce: Online retailers utilize FIDO for seamless checkout experiences, allowing customers to authenticate quickly and securely.
• Corporate Security: Organizations use FIDO to protect sensitive information and secure access to corporate networks and resources.
• Government Services: Many government agencies are adopting FIDO standards to enhance secure access to citizen services.

How to Keep your FIDO Safe?

Maintaining the security of FIDO authentication methods is crucial. Here are important practices to keep FIDO secure:

• Use Strong Biometrics: Choose devices that offer advanced biometric recognition, such as facial recognition or fingerprint scanning, and ensure these features are enabled.
• Keep Devices Updated: Regularly update the firmware and software on your devices to protect against vulnerabilities.
• Enable Two-Factor Authentication: Whenever possible, enable additional layers of authentication alongside FIDO for enhanced security.
• Secure Device Access: Use strong passwords or PINs to lock devices that store FIDO credentials, preventing unauthorized access.
• Be Aware of Phishing Attacks: Always verify the authenticity of the sites you are logging into, and avoid clicking on suspicious links.
