Abstract
The research literature on passwords is rich but little of it directly aids those charged with securing web-facing services or setting policies. With a view to improving this situation we examine questions of implementation choices, policy and administration using a combination of literature survey and first-principles reasoning to identify what works, what does not work, and what remains unknown. Some of our results are surprising. We find that offline attacks, the justification for great demands of user effort, occur in much more limited circumstances than is generally believed (and in only a minority of recently-reported breaches). We find that an enormous gap exists between the effort needed to withstand online and offline attacks, with probable safety occurring when a password can survive 106 and 1014 guesses respectively. In this gap, eight orders of magnitude wide, there is little return on user effort: exceeding the online threshold but falling short of the offline one represents wasted effort. We find that guessing resistance above the online threshold is also wasted at sites that store passwords in plaintext or reversibly encrypted: there is no attack scenario where the extra effort protects the account.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
