    Score password strength

    The zxcvbn engine (created by Dropbox) detects common patterns, dictionary words, keyboard sequences (qwerty, zxcvbn), dates, and l33t-speak substitutions. It returns a score from 0 (very weak) to 4 (very strong), estimated crack times for different attack scenarios, and actionable feedback. No AI can truly evaluate password strength. this engine uses real combinatorial analysis. Evaluates password strength using the Dropbox zxcvbn engine. Returns a 0-4 score, crack time estimates, and improvement suggestions

FAQ

Questions zxcvbn owners ask.

  • 01

    Why can't my AI evaluate password strength?

    AI checks superficial rules like 'has uppercase + number + symbol'. zxcvbn does combinatorial analysis. it knows 'P@ssw0rd' is just 'Password' with l33t substitutions, and rates it as weak despite passing every 'rule-based' check.

  • 02

    Is the password sent to any external server?

    No. 100% local. The embedded dictionary and pattern matching engine run entirely in-process. Zero network calls, zero data leakage, zero risk.

  • 03

    What do the crack time numbers actually mean?

    Four real attack scenarios: Online throttled (100/hour. most login pages), Online unthrottled (10/sec), Local slow hash (10K/sec. bcrypt), Local fast hash (10B/sec. MD5/SHA). Choose the scenario matching your system.
