Question 1

How is password strength calculated?

Accepted Answer

Strength is based on length, character variety (uppercase, lowercase, numbers, symbols), common patterns, dictionary words, and entropy calculation.

Question 2

How accurate is the crack time estimate?

Accepted Answer

The estimate assumes 10 billion guesses per second (modern GPU cluster). Actual crack time depends on the attacker's resources and method.

Question 3

Is my password sent to a server?

Accepted Answer

No. All analysis happens locally in your browser using JavaScript. Your password never leaves your device.

Question 4

What makes a strong password?

Accepted Answer

A strong password is at least 12 characters long, uses a mix of uppercase, lowercase, numbers, and symbols, and avoids common words or patterns.

Question 5

Does this check against leaked password databases?

Accepted Answer

This tool checks against common password patterns and dictionary words locally. It does not query external breach databases.
