"I regretted the minute I pressed share": a qualitative study of regrets on Facebook

TL;DR: Regrets associated with users' posts on a popular social networking site are investigated, based on a series of interviews, user diaries, and online surveys involving 569 American Facebook users whose regrets revolved around sensitive topics, content with strong sentiment, lies, and secrets.

Guess Again (and Again and Again): Measuring Password Strength by Simulating Password-Cracking Algorithms

TL;DR: An efficient distributed method is developed for calculating how effectively several heuristic password-guessing algorithms guess passwords, and the relationship between guess ability, as measured with password-cracking algorithms, and entropy estimates is investigated.
Proceedings ArticleDOI

Of passwords and people: measuring the effect of password-composition policies

TL;DR: A large-scale study investigates password strength, user behavior, and user sentiment across four password-composition policies, and describes the predictability of passwords by calculating their entropy, finding that a number of commonly held beliefs about password composition and strength are inaccurate.

Encountering stronger password requirements: user attitudes and behaviors

TL;DR: An entropy analysis is performed and it is shown that, although most of the users were annoyed by the need to create a complex password, they believe that they are now more secure and can be helpful in designing better password policies.

How does your password measure up? the effect of strength meters on password creation

TL;DR: It was found that meters with a variety of visual appearances led users to create longer passwords, however, significant increases in resistance to a password-cracking algorithm were only achieved using meters that scored passwords stringently.
