Research Questions#
•RQ1: What are the overall advantages and disadvantages of various passwordless authentication methods in terms of security and usability?
•RQ2: What specific challenges do users encounter when using passwordless authentication methods?
Methods Evaluated#
Biometric Authentication (Facial, Fingerprint, Retina)
One-Time Code Authentication (OTP)
Security Keys
Key Findings#
Usability vs Security
While biometrics offer convenience, privacy and accuracy remain concerns. OTPs are user-friendly but vulnerable to phishing, and security keys are highly secure but depend on physical devices.
User Adoption
Only 35% of participants were fully willing to use passwordless authentication without restrictions. 28% were open with certain conditions, highlighting that mistrust and fear of losing account access (24%) are significant hurdles.
Core Challenges
The research identified major concerns including mistrust (22%), lack of universal access (15%), and fear of others accessing the account (11%), which must be addressed for widespread adoption.
