Question 1

How is password strength calculated?

Accepted Answer

The tool analyzes password length, character variety (uppercase, lowercase, numbers, symbols), entropy bits, common patterns, dictionary words, and sequential characters to calculate a comprehensive strength score from 0 to 100.

Question 2

Is my password sent to any server?

Accepted Answer

No. All analysis happens entirely in your browser using JavaScript. Your password is never transmitted anywhere.

Question 3

What makes a strong password?

Accepted Answer

A strong password has 12+ characters, uses a mix of uppercase, lowercase, numbers, and symbols, avoids dictionary words and common patterns, and has high entropy (80+ bits).

Question 4

What is password entropy?

Accepted Answer

Entropy measures the randomness of a password in bits. Higher entropy means more possible combinations and harder to crack. A password with 80 bits of entropy has 2^80 possible combinations.
