The FIDO2 key is backward-compatible with the U2F protocol and is compatible with the latest Chrome browser on Windows, MacOS, and Linux. U2F may be used and secured on any website that adheres to the U2F protocol. FIDO2 allows users to quickly authenticate to internet services using common devices in both mobile and desktop contexts. The FIDO2 standards are the Web Authentication specification from the World Wide Web Consortium and the associated Client-to-Authenticator Protocol from the FIDO Alliance.

Fast Identity Online is the abbreviation for FIDO. With the addition of number two, this acronym is based on earlier work by the FIDO Alliance, most notably on the development of the Universal 2nd Factor (U2F) authentication standard. The FIDO Alliance’s third standard is after FIDO Universal Second Factor and FIDO Universal Authentication Framework. FIDO2’s primary goal is to remove the usage of passwords on the Internet. It was created to facilitate the introduction of open and royalty-free standards for secure, global authentication over the Internet. The FIDO2 authentication method removes the conventional security risks associated with using a username and password for login in favor of the FIDO2 passwordless login standard. As such, it safeguards against prevalent online threats such as phishing and man-in-the-middle assaults.

Strong customer authentication helps to increase the security of electronic payments. It utilizes multi-factor authentication to ensure that the account used for financial transactions is ours, thus minimizing the danger of fraud. SCA needs two-factor authentication and dynamic linkage, a message to the consumer that is unambiguous and unforgeable to ensure that the consumer is fully informed and has an active role in authorizing a financial transaction. In other words, under the new regulations, banks must get at least two authentication elements from customers. For example, a PIN or password typed on their mobile device would represent two factors; knowledge and ownership.
