Password Strength Auditor

Audit password entropy, crack time estimates, and vulnerability checks offline.

Evaluated strictly in your browser memory. Never transmitted over the internet.

SECURITY SCOREVery Strong (118 bits)
Estimated brute-force crack time: Billions of years

BEST PRACTICE CHECKLIST

At least 12 characters
Contains uppercase letters (A-Z)
Contains lowercase letters (a-z)
Contains numbers (0-9)
Contains special symbols (!@#$...)

Overview

Test how resilient your password is against brute-force attacks. Calculates entropy in bits, provides crack-time estimations, and highlights missing character requirements.

100% Private: All operations run locally on your device. Files never touch our servers.

Password Strength Meter: Crack Time & Entropy Evaluator

The Password Strength Checker evaluates password resilience against brute-force attacks, common dictionary patterns, and keyboard walks.

Computes estimated crack time and entropy bits in real time purely inside client memory.

How to Check Password Strength

Fast & Intuitive
1

Input Password

Type your credential string into the evaluation box.

2

Analyze Crack Time

Review the estimated time required for supercomputers to guess it.

3

Fortify Weak Points

Adopt suggestions like adding special symbols and length.
