Password Security Auditor

Acerca de esta herramienta

Evaluate the security of an entire list of passwords at once without sending them to any server — all processing is done locally in your browser. Paste passwords one per line into the input area and click Audit to receive a detailed security report for every password. Each entry receives a strength score from 0 to 100, a visual strength bar, and a letter grade (A–F). The entropy calculation shows bits of entropy based on character set size and password length, giving you a mathematical measure of guessing difficulty. Issue detection flags specific weaknesses: too short (under 8 or 12 characters), all lowercase, no numbers, no special characters, repeated character sequences, keyboard walk patterns (qwerty, asdf, 12345), and basic dictionary words (a built-in list of common English words). Every password is checked against a hard-coded list of the 100 most common passwords worldwide. The summary dashboard shows the overall security score across all passwords, the number of critical and warning-level issues, and highlights the worst offenders. Each password row shows personalized, actionable recommendations. Passwords are never logged or transmitted.
