Return to Passkeys Web Authentication (WebAuthn)

FIDO2 is a set of standards that enables passwordless authentication using hardware security keys and biometrics. It aims to provide a more secure and user-friendly alternative to traditional passwords. FIDO2 is based on two main specifications:

• **Web Authentication (WebAuthn):** A W3C standard that defines a browser API for interacting with FIDO2 authenticators.
• **Client to Authenticator Protocol (CTAP):** A FIDO Alliance specification that defines the communication protocol between the client device and the authenticator.

• **Passwordless Authentication:** FIDO2 eliminates the need for passwords, reducing the risk of phishing and password-related attacks.
• **Stronger Security:** FIDO2 uses public key cryptography and hardware-based authentication to provide a high level of security.
• **User Convenience:** FIDO2 allows users to authenticate with a simple touch or biometric gesture.
• **Cross-Platform Compatibility:** FIDO2 is designed to work across different platforms and devices.

• **Improved Security:** FIDO2 significantly reduces the risk of phishing, password reuse, and other password-related attacks.
• **Enhanced User Experience:** FIDO2 provides a convenient and user-friendly authentication experience.
• **Reduced Costs:** FIDO2 can help reduce the costs associated with password resets and account recovery.
• **Increased Productivity:** FIDO2 can improve productivity by eliminating the need for users to remember and enter passwords.
