This document summarizes research into user perceptions of biometric authentication methods and passwords from a user experience perspective. The research tested four hypotheses: 1) Perceptions of security do not align with objective data, 2) Passwords are perceived as secure despite weaknesses, 3) Less familiar methods are seen as less secure, 4) More important accounts lead to better password memory. The findings supported all hypotheses and showed design principles for secure yet convenient authentication should balance access, invasiveness, and desired friction.

Shared Trivial Reused Passwords In a recent study of 6 million user- generated passwords, the 10.000 most common ones accessed to 98.1% of all accounts. The human brain struggles to retain more than seven numbers in short-term memory. The average user has 26 password-protected accounts, but only 5 passwords.
