Description: FIDO2 is an authentication standard that allows users to access online services without passwords. This innovative approach is based on two-factor authentication and uses security devices, such as USB keys or biometric authentication, to verify the user’s identity. FIDO2 combines two main components: WebAuthn, which is a web API that allows browsers and applications to register and authenticate users using authentication devices, and CTAP (Client to Authenticator Protocol), which enables communication between the authentication device and the browser. The main advantage of FIDO2 is that it eliminates the need to remember complex passwords, reducing the risk of phishing attacks and the use of weak passwords. Additionally, FIDO2 provides a higher level of security by using public key cryptography, meaning that credentials are never stored on the server but are generated and stored locally on the user’s device. This approach not only enhances security but also simplifies the user experience, allowing for faster and safer access to various online platforms and services.
History: FIDO2 was developed by the FIDO Alliance (Fast IDentity Online), which was formed in 2012 with the goal of reducing reliance on passwords in online authentication. In 2018, FIDO2 was officially launched, which includes WebAuthn and CTAP, as an evolution of previous FIDO standards. This advancement was driven by the increasing need for more secure authentication solutions in a world where data breaches and phishing are becoming more common.
Uses: FIDO2 is primarily used in user authentication for online services, such as banks, social media platforms, and enterprise applications. It allows users to securely log in without needing to remember passwords, using authentication devices such as USB keys, mobile phones, or biometric authentication.
Examples: Examples of FIDO2 usage include logging into various online accounts that support this standard, allowing users to use security keys or biometric authentication to access their accounts. It is also used in applications that require an additional level of security to protect users’ sensitive information.
