![]() ![]() U2F (Universal 2nd Factor) was the original FIDO specification which, as the name suggests, was aimed at providing a commonly used means of strong authentication in addition to username and password. This is an extremely scalable model for making use of a high security public and private key-pair architecture, in which the private keys are never shared and can be thoroughly protected within dedicated security hardware in an authenticator.įIDO’s authentication protocol also enforces the verification of message origin, which makes it thoroughly resistant to phishing and man-in-the-middle attacks. The FIDO specification was designed to allow a single authenticator (key, token or device) to be used to secure access to many services, with each service using separate, unique and anonymous authentication codes. ![]() ![]() FIDO (Fast Identity Online) open standards for secure authentication are set by the FIDO Alliance, who’s members include Google, Microsoft, Mozilla, MasterCard, Visa and PayPal.
