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.
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]
Web Authentication (WebAuthn) is a web standard published by the World Wide Web Consortium (W3C). [1] [2] [3] WebAuthn is a core component of the FIDO2 Project under the guidance of the FIDO Alliance. [4]
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 ]
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.
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.
Rigor is a cornerstone quality of mathematics, and can play an important role in preventing mathematics from degenerating into fallacies. well-behaved An object is well-behaved (in contrast with being Pathological ) if it satisfies certain prevailing regularity properties, or if it conforms to mathematical intuition (even though intuition can ...
