Abstract

Fast Identity Online 2 (FIDO2) emerges as a transformative solution to the vulnerabilities inherent in traditional password-based authentication methods. Leveraging public key cryptography and authenticators, it establishes a passwordless authentication paradigm, extending its relevance beyond web applications to diverse realms such as online payments and government services. This paper explores FIDO2's emphasis on a seamless user experience while bolstering security measures through innovative credential management techniques. The acceptance of FIDO2 on major browsers ensures its usability on mobile devices, with most modern devices equipped to support FIDO2 authentication, thus expanding its reach and applicability. Additionally, its adoption by major tech companies and standards bodies underscores its credibility and potential for widespread adoption. However, challenges remain, including overcoming legacy systems, addressing compatibility issues, and ensuring user education. Despite these challenges, FIDO2 represents a significant advancement in online authentication, offering strong security, usability, and privacy features, positioning it as a key enabler of the passwordless authentication paradigm.
