WebAuthn
A web authentication standard defined by the W3C and a core component of the FIDO2 framework. It specifies the interaction protocol among browsers, operating systems, and authenticator devices, enabling passwordless authentication based on public-key cryptography.
Core Facts
Passkey is based on the W3C WebAuthn standard and the FIDO Alliance's FIDO2 specification, with asymmetric key encryption at its core, where the private key is securely stored on the device and never leaves it.
FIDO2 is a passwordless authentication standard jointly developed by the FIDO Alliance and W3C, comprising two core components: WebAuthn and CTAP.
FIDO2 is a passwordless authentication standard jointly developed by the FIDO Alliance and W3C, operating on the principle of asymmetric encryption.
Timeline (last 90 days)
FIDO2 is an industry standard jointly developed by the FIDO Alliance and W3C, and WebAuthn is the API specification within it targeting browsers and web applications.
Modern authentication systems (such as TOTP-based two-factor authentication, SMS verification codes, and FIDO2/WebAuthn hardware keys) are designed by nature to resist automated attacks, making it nearly impossible for AI agents to complete these verifications without possessing the user's physical device.
The authentication factors of two-factor authentication fall into three categories: something you know, something you have, and something you are; common implementations include TOTP, SMS verification codes, and hardware security keys (based on the FIDO2/WebAuthn standard).
FIDO2 is a passwordless authentication standard jointly developed by the FIDO Alliance and W3C, comprising two core components: WebAuthn and CTAP.
Traditional SMS OTP has been gradually replaced by more secure solutions such as TOTP, FIDO2/WebAuthn-standard hardware security keys, and on-device biometrics due to the risk of SIM card hijacking.
