Personalizing Password Policies and Strength Feedback

Hinweis der Redaktion

  1. An idea!
  2. PW are annoying prohpecy: passwords go away good! alternatives do not fully replace PWs
  3. less annoying: memorable, but insecure puts users at risk
  4. reduce risk: protect users example hassle, even more annoying failure: modify until met
  5. estimate strength / criteria password meter persuasive transparent goal, right time, right message, right way? high-value accounts
  6. = swiss army knife influence PW choice each user same policy universal solutions fail -> new approach
  7. we could turn to personality models big five, OCEAN tailor persuasive messages
  8. sign up scenario creative, abstract thinking, intellectual requirements would restrict creative abstract thinking better expression
  9. diligent, neat, organized, follow rules. harder rules, but better experience users won’t be lost with the task
  10. apart from policy adjust behavior of PW meters e.g. PW unique -> bar is full more quickly Personality traits
  11. finally, tailor suggestions to users randomly generated: not memorable own preferred style  support that example
  12. contextual cues
  13. first letter of sentence
  14. I propose, we create... If we utilize persuasive messages  personality has to be implemented happy to hear your thoughts
  15. looking forward to the discussion
