Study and Analysis of FIDO2 Passwordless Web Authentication

As cyberthreats evolve, traditional password-based authentication systems have proven inadequate. FIDO2 passwordless authentication offers a compelling solution, eliminating passwords while enhancing security and user experience. This survey examines FIDO2’s core components, integration with blockchain technology, accessibility for diverse devices, and comparative usability. Findings suggest FIDO2 delivers superior security and usability compared to passwords. However, challenges remain regarding standardization, privacy, and balancing security with convenience. Further research into multi-factor authentication, biometrics, cross-device functionality, and blockchain integration can advance FIDO2’s accessibility, security, and adoption. This analysis underscores FIDO2’s transformative potential to redefine authentication.
