The FIDO2 Project is a joint effort between the FIDO Alliance and the World Wide Web Consortium (W3C) whose goal is to create strong authentication for the web. At its core, FIDO2 consists of the W3C Web Authentication ( WebAuthn ) standard and the FIDO Client to Authenticator Protocol 2 (CTAP2). [ 6 ]
An authenticator that implements CTAP2 is called a FIDO2 authenticator (also called a WebAuthn authenticator). If that authenticator implements CTAP1/U2F as well, it is backward compatible with U2F. The protocol uses the CBOR binary data serialization format. The standard was adopted as ITU-T Recommendation X.1278. [6] [1]
First YubiKey USB token of the FIDO standard in 2014. The YubiKey is a hardware authentication device manufactured by Yubico to protect access to computers, networks, and online services that supports one-time passwords (OTP), public-key cryptography, authentication, and the Universal 2nd Factor (U2F) and FIDO2 protocols [1] developed by the FIDO Alliance.
Universal 2nd Factor (U2F) is an open standard that strengthens and simplifies two-factor authentication (2FA) using specialized Universal Serial Bus (USB) or near-field communication (NFC) devices based on similar security technology found in smart cards.
The authenticator is a FIDO2 authenticator, that is, it is assumed to be compatible with the WebAuthn Client; WebAuthn specifies how a claimant demonstrates possession and control of a FIDO2 authenticator to a verifier called the WebAuthn Relying Party.
Depending on the features, the key costs $25-$35, [2] but Google has provided them for free to high-risk users. [3] It is considered a more secure form of multi-factor authentication to log in to first-party and third-party services and to enroll in Google's advanced protection program.

Example of passwordless authentication with a passkey (Pixiv with Bitwarden) Passwordless authentication is an authentication method in which a user can log in to a computer system without entering (and having to remember) a password or any other knowledge-based secret.
